Four biased coins, A, B, C and D are thrown. The probability that each coin will land on Heads is shown below:

Coin A 0.33
Coin B 0.033
Coin C 1/3
Coin D 30%

(a) Which coin is most unlikely to land on Heads?

(b) Which coin is most likely to land on Heads?

(c) Coin B is going to be thrown 4000 times.
Work out an estimate for the number of times coin B will land on Heads
