If the probability of a student spending time reading is 0.10, the probability of spending time watching TV is 0.90 and the prob
joja [24]

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

Each month, Liz pays $35 to her phone company just to use the phone. Each text she sends costs her an additional $0.05. In March
Firdavs [7]
<h3><u>Answer:</u></h3><h3><u>752 & 617</u></h3><h3 /><h3><u>Explanation:</u></h3><h3><u>So if Liz pays $35 each month just to use the phone, we could subtract 35 from the total bill that month to get the the total cost she spent on text messages.</u></h3><h3 /><h3><u>March:$72.60-$35=$37.60</u></h3><h3><u>April: $65.85-$35=$30.85</u></h3><h3 /><h3><u>We can see that in March Liz spent $37.60 on texts in total and in April she spent $30.85 on texts in total. All we have to do is divide the amount of money she spent on texts( $37.60 & $30.85) by the cost of one text message($0.05) to get the amount of texts she sent that month.</u></h3><h3 /><h3><u>March: $37.60/$0.05=752</u></h3><h3><u>April: $30.85/$0.05=617</u></h3><h3 /><h3><u>Therefore, she sent 752 texts in March and 617 texts in April.</u></h3><h3 /><h3><u>~FrxziteTheLxoser~ I hoped I help you  :)</u></h3>
