Question

What is the probability of getting tails each time if a coin is tossed 4 times?

Answer 1

P(tails) = 0.5
P(tails 4 times in a row) = 0.5*0.5*0.5*0.5 = 1/16

Answer 2

thanks

Answer 3

If you look at the as the probability of getting 1 or more tail in 4 coin tosses, you would then calculate the probability of tossing 4 heads in a row and subracting that from 1. The probability fo tossing 4 heads is 1/2 * 1/2 * 1/2 *1/2 = 1/16. 1 - 1/16 = 15/16.

Answer 4

oh ok thank u
