Suppose you have 5 quarters and 5 pennies in your wallet. You select two coins from your wallet without looking. If the first coin is not replaced, what is the probability of selecting a quarter both times?

4/5

Step-by-step explanation:

If you have 5 quarters and 5 pennies the fraction would be... 5/5. If you take away two coins you would most likely take 1 penny and 1 quarter, which leaves 4 quarters. Therefore the answer is 4/5.

Hope this helps :)

50% it can be like you can pick 2 pennies you don't know that is why you have to look

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
