Answer:
The probability that components #1 and #2 fail, and at least one of components #3 and #4 fails is 0.031875
Step-by-step explanation:
Let's define the following events,
F1: Component #1 fails
F2: Component #2 fails
F3: Component #3 fails
F4: Component #4 fails
We are looking for the following probability
P[(F1∩F2)∩(F3∪F4)]
using distributive laws we have
P[(F1∩F2)∩(F3∪F4)] = P[(F1∩F2∩F3)∪(F1∩F2∩F4)] = P(F1∩F2∩F3) + P(F1∩F2∩F4) - P(F1∩F2∩F3∩F4) = P(F1)P(F2)P(F3) + P(F1)P(F2)P(F4) - P(F1)P(F2)P(F3)P(F4) = (0.25)(0.25)(0.3) + (0.25)(0.25)(0.3) - (0.25)(0.25)(0.3)(0.3)=0.031875
by the assumption of independence (the components fail independently) and because P(F1) = P(F2) = 0.25, P(F3) = P(F4) = 0.3
Answer: it is A
Step-by-step explanation:
because if you subtract 25 from 50 then add 35 and multiply by how many weeks he was there for you get your answer so the answer is A
<u><em>A: (50 - 25 + 35)m </em></u>
B: 35 + 50m - 25
C: 50 - 25 + 35m
D: 35m + 50 + 25
The carrot patch is a 2 by 5 rectangle so 2 times 5 is 10 so the answer is A
Answer:
Find out the how much does each pair of socks cost when bought individually .
To prove
Let us assume that the original price of one pair of shoes be x.
Than cost for three pair of shoes be 3x.
As given
Maritza is buying a multipack of 3 pairs is socks for $25.98.
She will save $6.39 by buying multipack instead of buying 3 individual pairs of the same socks.
Than the equation becomes
3x - 25.98 = 6.39
3x = 25.98 + 6.39
3x = 32.37
x = $10.79
Therefore each pair of socks cost when bought individually is $10.79 .
