Answer:

The probability is $\frac{5}{16}$

Step-by-step explanation:

Given is that a fair coin is tossed 5 times in a row.

This gives total number of outcomes as = $2\times2\times2\times2\times2=32$

As its needed that heads comes exactly 2 times, so favorable outcomes are = 5C2

$\frac{5!}{2!(5-2)!}$

Solving this we get 10

Therefore, the probability of getting heads exactly 2 times is =

$\frac{10}{32}$ or

$\frac{5}{16}$

3 1/2= 7/2= 7 divided by 2=

21/4=21 divided by 4=

$\sqrt[4]{21}$

4 goes into 21, five times which is 5 1/4

$\sqrt[2]{7}$

2 goes into 7, six times which is 6 1/2

Answer:

The distribution of average life time is approximately normallyl distributed with mean 20 hours and standard deviation of 0.4743 hours

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
