Question

Tickets numbered 1 - 10 are drawn at random and placed back in the pile. Find the probability that at least one ticketnumbered with a 6 is drawn if there are 4 drawings that occur. Round your answer to two decimal places.

Answer 1

The probability of a 6 being drawn in one pick is

`(1)/(10)`

For 4 drawings, the probability would be

`(1)/(10)+(1)/(10)+(1)/(10)+(1)/(10)=(4)/(10)=(2)/(5)=0.40`
