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.

You are going to toss 2 pennies 20 times how many times do you expect the 2 pennies will come up as 2 heads?
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.

Was the mass of 20 pennies equal to 20 times the mass of one penny?
In an ideal scenario, the mass of 20 pennies would be equal to 20 times the mass of one penny, assuming all pennies are identical and have the same mass.

Therefore, for most practical purposes, you can consider the mass of 20 pennies to be approximately equal to 20 times the mass of one penny.
