Jun and Deron are applying for the summer job at a local restaurant. The probability that Jun gets the job is 0.7, the probability that Deron gets the job is 0.4, the probability that at least one of them gets hired is 0.9. What is the probability that both Jun and Deron get hired

The probability that both Jun and Deron get hired=0.2

Step-by-step explanation:

Let

A=Jun

B=Deron

We are given that

The probability that Jun gets the job, P(A)=0.7

The probability that Deron gets the job, P(B)=0.4

The probability that at least one of them gets hired,

We have to find the probability that both Jun and Deron get hired.

We know that

Using the formula

Hence, the probability that both Jun and Deron get hired=0.2

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
