Assume the random variable x is normally distributed with mean u = 90 and standard deviation o=5. Find the indicated probability

Setler79 [48]

<u>Given</u>:

Let the random variable x is normally distributed with mean $\mu=90$ and $\sigma=5$

We need to determine the probability of $P(X$

<u>Probability of </u> $P(X$ <u>:</u>

The formula to determine the value of $P(X$ is given by

$Z=\frac{X-\mu}{\sigma}$

Thus, we have;

$P(X$

Simplifying, we get;

$P(X$

Using the normal distribution table, the value of -2 is given by 0.0228

$P(X$

Thus, the value of $P(X$ is 0.0228

If an event has a 55% chance of happening in one trial, how do I determine the chances of it happening more than once in 4 trial

aev [14]

The chances of it happening more than once in 4 trials is 13%

<h3>How to determine the number</h3>

From the information given, we have can deduce that;

Probability of 1 trial = 55%

= 55/ 100

Find the ratio

= 0. 55

We are to find the probability of it happening more than once in 4 different trials

If the probability of it happening in one trial is 555 which equals 0. 55

Then the probability of it happening in 1 in 4 trials is given as;

P(1/4 trials) = 1/ 4 × 55%

P(1/4 trials) = 1/ 4 × 0. 55

Put in decimal form

P(1/4 trials) = 0. 25 × 0. 55

P(1/4 trials) = 0. 138

But we have to know the percentage

= 0. 138 × 100

Multiply the values, we have

= 13. 8 %

Thus, the chances of it happening more than once in 4 trials is 13%
