Question

a bowler knocks down at least 6 pins 70% of the time. Out of 200 rolls, how many times can you predict the bowler will not down at least 6 pins?

Answer 1

Since he knocks at least 6 pins 70% of the time.

For 200 rolls:

70% of 200

= (70/100) * 200

= (7/10) * 200

= 140

140 times.

hope this helps :)
