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)
The equation would be 4(-22)-5
Sorry I do not know. Sorry to let you down
Answer:
It is C
Step-by-step explanation:
because 30/200 simplifies to 3/20 and you multiply that times 17000
and get 2550
4.4 is not a whole number so it isn’t the largest number that is also less than 4.5. The correct answer could be 4
