Question

Elisa has 10 gold colored coins and 6 silver colored coins. She selects 2 coins with replacement. What is the probability she selects 2 silver colored coins.

Answer 1

Explanation:

p=number of silver coins/total number of coins

p=3/8 of 3/8=9/64

Answer 2

Answer:
`(9)/(64)`

Explanation:

n(gold colored coins) = 10

n(silver colored coins) = 6

Total number of coins = 16

since there is replacement , the probability she selects 2 silver colored coins will be :

`(6)/(16)` x
`(6)/(16)`

=
`(3)/(8)` x
`(3)/(8)`

=
`(9)/(64)`

Therefore : the probability she selects 2 silver colored coins is
`(9)/(64)`
