Find the indicated probabilities.

Then determine if the event is unusual.

Explain your reasoning.

You play nine games of rock-paper-scissors.

Find the probability that the number of games you win is (a) exactly

Part 1
(a) The probability that the number of games you win is exactly
three
is …. ?

The event (is not/ is) unusual because it (is not/ is) less than or equal to
0.05

(Round to three decimal places as needed)


Part 2
(b) The probability that the number of games you win is more than
six is ….?

The event (is/ is not) unusual because it (is/ is not) less than or equal to 0.05

(Round to three decimal places as needed)


Part 3
(c) The probability that the number of games you win is less than four is …?
The event (is not/ is) unusual because it (is not/ is) less than or equal to 0.05
