The probability of it landing heads up at least three times is 1/4.
According to the statement
We have a given that the coin is tossed 4 times And we have to find the probability of it landing heads up at least three times.
So, we know that the
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.
So, According to the statement
Coin is tossed 4 times and we have to probability of find heads three times it means n = 3.
To get 3 heads, means that one gets only one tail. This tail can be either the 1st coin, the 2nd coin, the 3rd, or the 4th coin.
Thus there are only 4 outcomes which have three heads.
The probability is 4/16 = 1/4.
So, The probability of it landing heads up at least three times is 1/4.
