Question

If each face on a standard die shows a number,1,2,3,4, 5 or 6.If the die is tossed 30 times, how many times would you expect to get 3.

Answer 1

We should get a 3 about 5 times

Explanation:

Possible outcomes 1,2,3,4,5,6

P(3) = number of 3's / total = 1/6

Expect a 3 = number of rolls * probability of a three

= 30 * 1/6

=5
