(88 + 92 + 96 + x) / 4 = 90
(276 + x) / 4 = 90
276 + x = 90 * 4
276 + x = 360
x = 360 - 276
x = 84 <=== he would need an 84
Answer:
Step-by-step explanation:
First, we need to add all the jellybeans together to find the chances of a specific bean per type out of all of them.
42 + 45 + 20 + 32 = 139 beans
So now we have to decide individually the probabilities of the two types
The probability of getting a purple bean is equal to
32/139 and the probability of NOT getting a red bean is equal to
97/139
So now you just add them together:
32 + 97 = 129/139
And the percentage of that would be approximately 92.81%
