\frac{8}{7} - \frac{1}{3} = \frac{17}{21}

because in order to solve you need to get the common denominator, which in this case is 21...

\frac{3}{3} ( \frac{8}{7} ) = \frac{24}{21}

\frac{7}{7} ( \frac{1}{3} ) = \frac{7}{21}

and now that you have a common denominator you can complete the operation...

\frac{24}{21} - \frac{7}{21} = \frac{17}{21}

Answer:

3.37 times

Step-by-step explanation:

Probability of hitting and odd number= 3/5

Probability of hitting and odd number=2/5

Probability of hitting and odd number three times= (3/5)^3

Probability of hitting and odd number three times=(2/5)^3

Now

(3/5)^3 / (2/5)^3 = 3.37

Hence Probability of hitting an odd number three times is 3.37 times more than the probability of hitting an even number three times !
