A = event that the ball drawn from urn #1 is white
B = event that the ball drawn from urn #2 is white
P(A) = probability of event A
P(A) = (number of white in urn #1)/(number total in urn #1)
P(A) = 3/(3+6)
P(A) = 3/9
P(A) = 1/3
P(B) = probability of event B
P(B) = (number of white in urn #2)/(number total in urn #2)
P(B) = 3/(3+8)
P(B) = 3/11
Because A and B are independent events, we can multiply the probabilities
P(A and B) = P(A)*P(B)
P(A and B) = (1/3)*(3/11)
P(A and B) = (1*3)/(3*11)
P(A and B) = 1/11
Answer: Choice A) 1/11

Answer:
20 pieces of tape.
Step-by-step explanation:
Okay, so first you have to realize that 1/4 of a foot means there is 4 pieces in a foot. So at this point you need to say there is 5 groups of four because 4 pieces of tape in a foot. So 5 times 4 is 20 pieces of tape.

Answer:
Step-by-step explanation:
First we need to find the total amount of apples in the crate:
Total = 10 + 14 + 4 + 18 = 46 apples
The probability of the first apple being a golden delicious apple is the number of those apples over the total number of apples:
Then, the probability of the second apple being a granny Smith apple is the number of those apples over the total number of apples, but now the total number of apples is one less, because one apple was removed from the crate:
The final probability we want is the product of those two probabilities:
