Question

PLEASE HELP!!!!!

Answer 1

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%

Answer 2

Answer:

$\frac{129}{139}$

Step-by-step explanation:

Given,

In the bag,

Red candies = 42,

Green candies = 45,

Yellow candies = 20,

Purple candies = 32,

So, the total candies = 42+45+20+32=139

⇒ The probability of purple candies = $\frac{32}{139}$

Also, the probability of red candies = $\frac{42}{139}$

⇒ The probability that candy is not red = 1 - the probability of red candies

$=1-\frac{42}{139}$

$=\frac{139-42}{139}=\frac{97}{139}$

Hence, the probability that it is purple or not red is,

P (purple or not red) = The probability of purple candies + The probability that candy is not red

$=\frac{32}{139}+\frac{97}{139}$

$=\frac{129}{139}$
