X/9+3=7 should be the answer unless it’s 9/x+3=7. It’s most likely the first one.

As reported in Trends in Television, the proportion of US households who have at least one VCR is 0.535. If 14 households are se

Using the binomial distribution, it is found that there is a 0.5601 = 56.01% probability that the number having at least one VCR is no more than 8 but at least 6.00.

For each household, there are only two possible outcomes. Either it has at least one VCR, or it does not. The probability of a household having at least one VCR is independent of any other household, which means that the binomial distribution is used to solve this question.

Binomial probability distribution

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.
n is the number of trials.
p is the probability of a success on a single trial.

In this problem:

14 households, hence $n = 14$ .
0.535 probability of having at least one VCR, hence $p = 0.535$ .

The probability of <u>at least 6 and no more than 8</u> is:

$P(6 \leq X \leq 8) = P(X = 6) + P(X = 7) + P(X = 8)$

In which:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 6) = C_{14,6}.(0.535)^{6}.(0.465)^{8} = 0.1539$

$P(X = 7) = C_{14,7}.(0.535)^{7}.(0.465)^{7} = 0.2024$

$P(X = 8) = C_{14,8}.(0.535)^{8}.(0.465)^{6} = 0.2038$

Then:

$P(6 \leq X \leq 8) = P(X = 6) + P(X = 7) + P(X = 8) = 0.1539 + 0.2024 + 0.2038 = 0.5601$

0.5601 = 56.01% probability that the number having at least one VCR is no more than 8 but at least 6.00.

Answer:

Solution of the given expression is 26

Solution of the given expression is 8.67

Step-by-step explanation:

Given:

a] $4\frac{1}{3} \times 6$

b] $2\frac{3}{5} \times 3\frac{1}{3}$

Find the solution;

Computation:

a] $4\frac{1}{3} \times 6$

Step 1 ;

Changed mixed fraction into simple fraction

⇒ 13/3 x 6

Step 2 ;

⇒ 13 x 2

26

Solution of the given expression is 26

b] $2\frac{3}{5} \times 3\frac{1}{3}$

Step 1 ;

Changed mixed fraction into simple fraction

⇒ (13/5) x (10/3)

Step 2 ;

⇒ 130 / 15

8.67

Solution of the given expression is 8.67
