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)
1+5=6 so 6/8
Simplifying 6/8 is 3/4
He currently does 8, and is increasing by 2, so our equation will be
2x+8=30
Subtract the 8 over
2x=22
Divide by 2 on both sides
X=11
It will take 11 days
Answer:
approximately 25 weeks
Step-by-step explanation:
take $ 5000-$ 1325=$3675 this is what is remaining to achieve $5000
if you get $150 in one week what about $3675 is equal to how many weeks
$150=1 week
$3675=??weeks
<u>$</u><u>3675</u><u> </u><u>×</u><u> </u><u>1 week</u>
<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>$</u><u>150</u>
<u> </u><u> </u><u> </u>
<u>Ans</u><u> </u><u>=</u><u>24</u><u>.</u><u>5</u><u> </u><u>the</u><u> </u><u>same</u><u> </u><u>as</u><u> </u><u>25</u><u> </u><u>weeks</u>
