Tom is making plum crumble. For the crumble topping, he uses sugar, butter and flour in the ratio 2 : 3 : 5 Tom uses 250g of plums for every 400g of crumble topping. Tom has 0.5kg of plums. He uses all of them. Work out how much sugar, butter and flour he needs for the crumble topping. PLEASE I NEED EXPLANATION I ALREADY KNOW ANSWER Ans-sugar 160g butter-240g Flour-400g

the answer will be b x² +x-1

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

parallelogram is the   answer
