What is the probability you will get one tail? Toss a coin three times

3/8

Step-by-step explanation:

We want the probability of getting a tail in three trials.

We will use binomial distribution, given by the formula:

We want one success out of three trials. So, n = 3 and x = 1.

The probability for success in one trial is 1/2. So, p = 1/2.

And the probability for failure in one trial is 1/2. q = 1/2.

Therefore, the probability of getting a tail is:

Evaluate:

The probability of getting a tail by tossing a coin thrice is 3/8.

Edit:

My apologies. If you haven't learned the binomial distribution yet, below is another method.

Using the fundamental counting principle, we have a total of 2 times 2 times 2 or 8 total outcomes.

We want only one tail. This can be the first toss, the second toss, or the third toss.

So, out of 8 total outcomes, only 3 are favorable.

Hence, the probability of getting one tail by tossing a coin thrice is 3/8.

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140

sure thing bud

hope this
