Adam can earn money recycling aluminium cans .each can weighs 15g and he can get paid 50p per kg . if adam earns £15 , how many cans has he recycled?

Our first step in solving this would to calculate the total weight in kilograms for the cans recycled.

Let us assume that "X" is the total weight of cans recycled.

X*0.50 = 15

X = 15/0.5 = 30

Weight of Cans recycled = 30Kg

we know that 1 kg is 1000 grams, so 30 Kg should be = 30*1000 = 30,000 grams

Since each can weighs 15 grams, the total number of cans recycled = 30,000/15 = 2,000 cans

Total number of cans recycled = 2,000 cans

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
