Step-by-step explanation:
Nø of sample space, n(s) = 40
nø of unripe oranges, n (u) = 12
no of ripe oranges, n (r) = 40 - 12 = 28
Now
The probability that it is ripe is, P(E)
= n(r) / n(s)
= 28 / 40
= 7 / 10
Also the probability that it is unripe is, P(E)
= n(u) / n(s)
= 12 / 40
= 3 / 10

There are 4 quarts in 1 gallon, so a rate of 120 gallons per minute converts to 4 x 120 = 480 quarts per minute. To find the per hour rate, we simply multiply our per minute rate by 60, obtaining 480 x 60 = 28800 quarts per hour.
Answer:
The equal amount is 525
.
Step-by-step explanation:
Given that,
Eric and his two sister shared amount of money in ratio2:7 respectively.
Amount with Eric = 300
It means,
2x = 300
x = 150
So,
7x = 7(150)
= 1050
As the remaining amount shared equally among the sister. So, the equal amount is 525
.
