Answer:
f^-1 (x) = x/4
Step-by-step explanation:
Answer:
P(A or B) = P(A) + P(B) - P(A and B) = 0.5 + 0.7 - 0.3 = 0.9
Step-by-step explanation:
The equation we should use to calculate the addition of probabilities is:
P(A or B) = P(A) + P(B) - P(A and B)
Notice that if we just sum P(A) + P(B), our result would be wrong, because we would sum the intersection of those events two times.
So, in this case, if we call 'A' the pillow being encased in microfiber and 'B' the pillow being filled with memory foam, we have that:
P(A) = 0.5
P(B) = 0.7
P(A and B) = 0.3
So the addition of both probabilities is:
P(A or B) = 0.5 + 0.7 - 0.3 = 0.9
£3000 x 0.4 to the power of 3= £192
£192 + £3000 = £3192
