Buffy ate 100 fries in 5 minutes find her fry-eating rate in fries per minute

Paul [167]

Answer:

20 fries per minute.

Step-by-step explanation:

If you express the number of fries per minute as 100/5 (as there are 5 minutes and 100 fries), assuming she ate at the same rate per minute, she had 20 fries per minute.

To check, multiply 20 by 5, in order to find out her fries per 5 minutes. It should be equal to 100.

A binomial experiment has 4 trials in which p = 0.4. What is the probability of 3 successes?

Kaylis [27]

The probability of 3 successes is 0.0384

<h3>How to determine the probability?</h3>

The given parameters are:

Trials, n = 4
Probability of success, p = 0.4

The binomial probability is represented as:

$P(x) = ^nC_x * p^x * (1 - p)^{n-x$

So, the probability of three successes is:

$P(3) = ^4C_3 * 0.4^3 * (1 - 0.4)^{4 -3$

Evaluate the factors in the expression

$P(3) = ^4C_3 * 0.0384$

Evaluate the combination expression

P(3) = 1 * 0.0384

Evaluate the product

P(3) = 0.0384

Hence, the probability of 3 successes is 0.0384
