At the mall, buying a pair of shoes and buying a book are independent events.The probability that a shopper buys shoes is 0.15.

IRISSAK [1]

Answer:

The probability that a shopper buys shoes and a book is 0.015

Step-by-step explanation:

we are given

The probability that a shopper buys shoes is 0.15

so, we have

$p(s)=0.15$

The probability that a shopper buys a book is 0.10

so, we have

$p(b)=0.10$

the probability that a shopper buys shoes and a book can be written as

p(s∩b)

we are given that

s and b are independent

so,

p(s∩b) $=p(s)\times p(b)$

now, we can plug values

p(s∩b) $=0.15\times 0.10$

p(s∩b) $=0.015$
