Question

A bowler knocks down at least 6 pins 70 percent of the time. Out of 200 rolls, how many times can you predict the bowler will knock 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.

Answer 2

I think that for this you just find 70% of the 200 rolls. So 70% of 200=140. So you predict that the bowler will knock down 6 pins 140 times. To find 70% you will just knock off a zero to find 10% then times it by 7. I hope that this was helpful.
