There are three outcomes of 4 out of eighteen outcomes, so the fraction of angle of spinner numbered 4 is \frac{3}{8}

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

A circle is divided into 9 uneven pie shaped pieces.

Each section is labeled 1 to 9.

When the circle is spun and the number pointing north it will be recorded:

4 3 2 1 9 8 5 6 7 4 3 2 1 5 8 6 5 4

We need to find the central angle of the section labeled 4.

Number of times 4 occur= 3

Total number of times it has been recorded = 18

So, Probability of getting "4" is given by

\frac{\text{Numberof favourable outcomes}}{\text{Total number of outcomes }}\\\\=\frac{3}{18}\\\\=\frac{1}{6}

Hence, Option 'B' is correct.

Find the indicated conditional probability
andrezito [222]

Given:

The two way table.

To find:

The conditional probability of P(Drive to school | Senior).

Solution:

The conditional probability is defined as:

P(A|B)=\dfrac{P(A\cap B)}{P(B)}

Using this formula, we get

P(\text{Drive to school }|\text{ Senior})=\dfrac{P(\text{Drive to school and senior})}{P(\text{Senior})}                      ...(i)

From the given two way table, we get

Drive to school and senior = 25

Senior = 25+5+5

           = 35

Total = 2+25+3+13+20+2+25+5+5

         = 100

Now,

P(\text{Drive to school and senior})=\dfrac{25}{100}

P(\text{Senior})=\dfrac{35}{100}

Substituting these values in (i), we get

P(\text{Drive to school }|\text{ Senior})=\dfrac{\dfrac{25}{100}}{\dfrac{35}{100}}

P(\text{Drive to school }|\text{ Senior})=\dfrac{25}{35}

P(\text{Drive to school }|\text{ Senior})=0.7142857

P(\text{Drive to school }|\text{ Senior})\approx 0.71

Therefore, the required conditional probability is 0.71.
