Assuming they are dice, to work out the probability that the product is 8, the dice either have to be 2 and 4 or 4 and 2. The blue dice therefore has to be a 2 (4 is not less than 3), which is a 1 in 6 probability. The yellow one therefore has to be 4, which again is 1 in 6. The probablility that these both happen at the same time is given when they are multiplied together.

Answer:
3x(3x + 2)
Step-by-step explanation:
4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
First, we get rid of the negative exponent in the parenthesis. We do this by moving it to the top. Our equation is now:
Next, we can cross out one n from both the top and the bottom.
Finally, we evaluate the -2
Our equation becomes:
This becomes:
This can not be simplified any further, so this is the final answer.
Answer:
A) P(E|F) = 0.900
B) P(F|E) = 0.771
Step-by-step explanation:
P(E) = 0.7
P(F) = 0.6
P(E n F) = 0.54
A) P(E|F), the probability that the first airline's flight is fully booked given that the second airline's flight is fully booked is given mathematically as
P(E|F) = P(E n F)/P(F) = 0.54/0.6 = 0.900
B) P(F|E), the probability that the second airline's flight is fully booked given that the first airline's flight is fully booked is given mathematically as
P(F|E) = P(E n F)/P(E) = 0.54/0.7 = 0.771
