Question

Please help me figure out this probability problem!!!

Answer 1

10 + 5 + 1 is 16. There are 10 red balls, and there are 16 balls altogether. If you’re asking for a fraction, it would be 10/16. 10/16 as a simplified fraction is 5/8. The probability that the first ball is red is 5/8. There is one black ball, and 16 altogether. If you’re asking for a fraction, it would be 1/16. 1/16 can’t be simplified anymore because it is already in its lowest terms. So the probability of drawing out a black ball is 1/16.
So your answers are....

First ball being red: 5/8

Second ball being black: 1/16

Hoped this helped. Have a nice day!

Answer 2

10 + 5 + 1 = 16 - all balls
The probability that the first ball is red:
`P(R)=(10)/(16)=(5)/(8)`
The probability that the second ball is black:
`P(B)=(1)/(15)`
Together:
`P(R)\cdot P(B)=(5)/(8)\cdot(1)/(15)=(1)/(24)`
