What is the probability of getting a yellow marble?
2 Answers By Expert Tutors
There are a total of 16 marbles and 7 are yellow. The first marble selected has a 7 in 16 chance of being selected. In other words 7/16 (seven divided by sixteen), which is 0.4375. Multiply it by 100 to get percent probability of 43.75%.
What is the probability that the marble will be green?
The probability that the marble is either red or green is 0.8.
What is the probability of selecting a white marble?
The probability of selecting a white marble is 1/3 .
What is the formula of probability?
In general, the probability is the ratio of the number of favorable outcomes to the total outcomes in that sample space. It is expressed as, Probability of an event P(E) = (Number of favorable outcomes) ÷ (Sample space).
How do you calculate probability example?
For example, if the number of desired outcomes divided by the number of possible events is . 25, multiply the answer by 100 to get 25%. If you have the odds of a particular outcome in percent form, divide the percentage by 100 and then multiply it by the number of events to get the probability.
What is the probability of getting a number divisible by 7?
The probability that a random number is divisible by 7 is obviously 1 in 7.
What is the probability that the marble will be any Colour?
HENCE, the probability of getting any one colour is 1.
How many marbles are in a bag?

What is an example of a probability?
Probability is the likelihood or chance of an event occurring. For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). ... The probability of something which is impossible to happen is 0.
How do you calculate the number of possible outcomes?
To find the total number of outcomes for two or more events, multiply the number of outcomes for each event together. This is called the product rule for counting because it involves multiplying to find a product.
What is the probability of picking a green?
A box contains two red balls and four green balls. If we randomly select a ball from the box: The chance of drawing a red ball is 2/6 = 1/3. The chance of drawing a green ball is 4/6 = 2/3.
What is the probability of year 2021 having 53 Sundays?
In 365 days, Number of weeks = 52 weeks and 1 day is remaining. 1 remaining day can be Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday. Total of 7 outcomes, the favourable outcome is 1. ∴ probability of getting 53 Sundays = 1 / 7.
What is the probability that the spinner will land on a number 3?
The probability of spinning a 3 is also 2 / 8 .
