Answer:

The probability is 0.97

Step-by-step explanation:

In this question, we are concerned with calculating the probability of a student spending time reading or watching TV.

To calculate this, we simply use a direct mathematical formula.

P( of spending time reading or watching tv) = P(of spending time reading) + P(spending time watching Tv) - P( of spending time watching Tv and reading)

From the question, we identify the probabilities as follows;

P(spending time reading) = 0.1

P(of spending time watching Tv) = 0.9

P(of spending time watching Tv and reading) = 0.03

Now, plugging these values, we have

P( of spending time reading or watching Tv) = 0.9 + 0.1 -0.03

= 1-0.03 = 0.97

Answer: The answer is 3/8

Step-by-step explanation: First you figure out your expression: 7/8 - 1/2. Then you find a common denominator, which will be 8. To make one-half have a denominator of 8, multiply by 4/4. 1/2*4/4=4/8. To finish, subtract 7/8-4/8 and you get 3/8.
