A jar on your desk contains 14 black, 9 red, 13 yellow, and 2 green jellybeans. You pick a jellybean without looking. Write the probability as a reduced fraction.

A) Find the probability that it is not red jellybeans.

B) Find the odds of picking not red jellybeans.

Solution

Solution

Total no of jellybeans are = 14+9+13+2 = 38

no of red jellybeans = 9

therefore , probability of picking a jellybean ( say is denoted by P(E) ) = 9/38

=> probability of not picking a red jelly bean is = 1- 9/38 = 29/38 = 0.76316

B) the odds of not picking jellybeans are : 29 : 9
