Step-by-step explanation:
Answer:
a) 0.8836
b) 0.7339
c) 0.2342
Step-by-step explanation:
Books classified as fiction = 94% or 0.94 probability
Books classified as non-fiction = 1 - 0.94 = 0.06
a) for two books, we get: 0.94 * 0.94 = 0.8836 Probability
b) The probability that all five books are fiction is: 0.94^5
This equals 0.7339 Probability
c) Probability that one books is non-fiction, while the other 4 are fiction is determined in the following way:
Probability of non-fiction * probability of fiction^(number of books)
0.06 * 0.94^4 = 0.0468
This does not account for the order at which the non-fiction book shows up. Such as the non-fiction book being the first book picked, or in another case - the non-fiction book being the last picked.
Since there are 5 ways this could occur, the total probability will be calculated as shown: 0.0468 * 5 = 0.2342 Probability
100 ml of fruit squash
sum the parts of the ratio, that is 2 + 7 = 9 parts
divide 450 ml by 9 to find 1 part
1 part =
= 50 ml
squash is 2 parts = 2 × 50 = 100 ml
lemonade is 7 parts = 7 × 50 = 350 ml
total = 100 + 350 = 450 ml
