Answer:

f(x) = 30 - 5x \\ f(x) = 0 \\ 30 - 5x = 0 \\ 30 = 5x \\ 5x = 30 \\ x =  \frac{30}{5}  \\   \purple{\boxed{ \red{x = 6}}}

A bag contains 5 white, 3 black, and 2 green balls. Balls are picked at random.
Soloha48 [4]

Answer:

look down there

Step-by-step explanation:

First ball:

Probability of drawing a white ball is 5/8

Probability of drawing a black ball is 3/8

Second ball:

This depends on the first ball drawn, lets say you drew a white ball initially, 4 white balls are left out of 7 balls in total. The probability of a white ball in the second pick is 4/7.

Total probability of drawing two white balls is 5/8*4/7 (since they are independent events).

If you picked a black ball initially, picking another black ball would have a probability of 2/7, on similar grounds , total prob for 2 blacks would be 3/8*2/7.

The probability that you pick 2 balls of same color is (5/14 + 3/28) = 13/28. (Since they are mutually exclusive events)
