Question

6 purple marbles & 8 green-no replacement: Solve P(purple, purple)

Answer 1

`P(purple)=(15)/(91)`

Explanation:

-The probability of both being purple is equivalent to the P(purple) times P(purple) in the second.

-The probability can therefore be calculated as follows;

`P(purple)=P(purple)_1+P(purple)_2\\\\=(6)/(14)* (5)/(13)\\\\=(15)/(91)`

Hence, the probability of both marbles being purple is
`(15)/(91)`
