Answer 2

Given:

During a bowling practice, Marley managed to roll 14 strikes out of 70 attempts.

To find:

Percentage of Marley's attempts which were strikes ( Sucess Percentage).

Solution:

1. It is given that Marley managed to make 14 strikes out of 70 attempts.

2. Percentage is defined as the number of favorable parts out of 100 parts,

Example: 1 favorable part out of 100 implies 1 percentage.

3. Percentage can also be defined as the ratio of the total favorable events by the total number of events multiplied by 100.

Example: 2 favorable events out of 10 events implies $\frac{2}{10}*100$which is 20 percent.

4. Percentage is denoted by %.

5. Using the formula from Point 3 we get,

=> Percentage of strikes =100* (Total number of strikes)/(Total number of attempts).

=> Percentage of successful strikes = 100*(14/70)

=> Percentage of successful strikes = 20%.

Therefore the percentage of Marley's attempts which were stikes is 20%.
