A study shows that 14%14\% of shoppers use reusable bags when shopping. You randomly ask shoppers, one at a time, whether they use reusable bags. Let the random variable XX represent the first trial where a shopper uses reusable bags. Find the probability that the first user is the fourth or fifth person you ask. Also, determine whether this event is unusual.

P(4≤X≤5)=0.166P(4\leq X\leq5)=0.166The event is not unusual

P(4≤X≤5)=0.051P(4\leq X\leq5)=0.051The event is not unusual

P(4≤X≤5)=0.016P(4\leq X\leq5)=0.016The event is unusual

P(4≤X≤5)=0.197P(4\leq X\leq5)=0.197The event is unusual

Problem 82Multiple Choice

A study shows that $14 percent sign$ of shoppers use reusable bags when shopping. You randomly ask shoppers, one at a time, whether they use reusable bags. Let the random variable $X$ represent the first trial where a shopper uses reusable bags. Find the probability that the first user is the fourth or fifth person you ask. Also, determine whether this event is unusual.

$P of open paren 4 is less than or equal to X is less than or equal to 5 close paren equals 0.051$

The event is not unusual

$P of open paren 4 is less than or equal to X is less than or equal to 5 close paren equals 0.016$

The event is unusual

$P of open paren 4 is less than or equal to X is less than or equal to 5 close paren equals 0.197$

The event is unusual

$P of open paren 4 is less than or equal to X is less than or equal to 5 close paren equals 0.166$

The event is not unusual
