Three rats in a lab are injected a type of medicine. The independent probabilities for each rat exhibiting side effects are 0.5,

EleoNora [17]

Step-by-step explanation:

There are four possible values of X: 0 rats show side effects, 1 rat shows side effects, 2 rats show side effects, or all 3 rats show side effects.

Probability X = 0:

P = (1 − 0.5) (1 − 0.4) (1 − 0.3)

P = 0.21

Probability X = 1:

P = (0.5) (1 − 0.4) (1 − 0.3) + (1 − 0.5) (0.4) (1 − 0.3) + (1 − 0.5) (1 − 0.4) (0.3)

P = 0.44

Probability X = 2:

P = (0.5) (0.4) (1 − 0.3) + (0.5) (1 − 0.4) (0.3) + (1 − 0.5) (0.4) (0.3)

P = 0.29

Probability X = 3:

P = (0.5) (0.4) (0.3)

P = 0.06

Kevin has 16 ounce can of mixed nuts he gives 1/2 of the mixed nuts to his sister. He then eats 3/4 of the remaining nuts. How m

mixas84 [53]

Kevin will be left with 2 ounces of mixed nuts in the can

Step-by-step explanation:

Given

Total nuts = 16 ounces

As Kevin gave 1/2 of the nuts to his sister, he will be left with

$= \frac{1}{2} * 16\\= 8$

He is left with 8 ounces of mixed nuts

The he eats 3/4 of the remaining

$= \frac{3}{4} * 8 \\= 6\ ounces$

so he is left with 8 - 6 = 2 ounces of mixed nuts

Hence

Kevin will be left with 2 ounces of mixed nuts in the can
