Each time you toss two pennies, there are four ways they can land: H H H T T H T T One of the four ways is (Heads - Heads), so the probability of 2 heads is 1/4 or 25% . If the pennies are 'fair' (not loaded), and you toss them a large number of times, you should expect 2 heads roughly 1/4 of the time. Out of 20 tosses, that's 5 times. But don't bet on it.

Toss a coin 20 times and see what happens.It is POSSIBLE to always get 10 heads and 10 tails...but it is not very PROBABLE.
20 cents is twenty pennies.

5 times.When tossing 2 pennies there are 4 equiprobable outcomes or events with 1/4 ofprobability for each to happen:P(H,H) = 1/4P(H,T) = 1/4P(T,H) = 1/4P(T,T) = 1/4So if you toss 2 pennies 20 times, the "expected" number of times that 2 heads (H,H)will come up is 1/4 of the 20 times, that is 5 times.

240- there were 12 pennies in a shilling and 20 shillings in a pound.
20 cents is twenty pennies.
100 pennies = 1 British Pound 2,000 pennies = 20 British Pounds
Yes but the probability for that is 1/3,656,158,440,062,976. In other words, it's probably not going to happen
