If 20 coins are tossed, find the probability that they'll all land on tails.

Mathematics
1 answer:
Svetach [21]3 years ago
5 0
The odds of 1 coin landing tails is 1/2, for 2 coins it would be 1/4, 3 would be 1/8, 4 would be 1/16, etc.

the way you find this is by doing 1/2^n where n is the number of coins you have. if you plug in 20, you get 1/1,048,576

3/70

Step-by-step explanation:

change 1/10 and 1/7 so the denominator (bottom number) is the same.  1/10= 7/70 and 1/7= 10/70 so you need 3/70 to make the two numbers equal.
