Given the condition that you know a student has purchased at least one of the items. What is the probability as a percentage that they purchased only one of the items?

Step-by-step explanation:

This is a case of conditional probability, in which we have to find the probability of ocurance of event E when when event F has already ocured.

To find the probability of at least one of something, calculate the probability of none and then subtract that result from 1.

That is, P(at least one) = 1 – P(none)

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

is should be y = 5x
