If you have 9 quaters and 21 pennies, in percents, what is the chance that you will pick a penny out is a hat?

We know that you have 9 quarters

We also know that you have 21 pennies

Probability is represented as "determined factor" / total

First, we need to find the total amount of possibilities. This means that you have to add 21 and 9

21 + 9 = 30

We want to know the probability of picking a penny out of the hat, so you would represent this as:

21/30

To turn it into a percent, divide 21 by 30.

21 ÷ 30 = 0.7

0.7 is equivalent to 70% as a percent

This means that you will have a 70% chance of picking a penny out

70%

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
