Rainbow [258]

Question seem incorrect because 60%,50% and 20% sum up to more than a 100% therefore we've made a little correction

Answer:

0.8

Step-by-step explanation:

Probability = number of favorable outcomes/number of outcomes

Given that 30% are entertained by reading books

50% are entertained by watching TV

20% are entertained by reading books and watching TV

The probability that a person will be entertained by books or TV =

30/100+50/100= 3/10+5/10

=8/10

=0.8

*30 POINTS* In a group of 53 children, 22 had a dog, 18 had a cat, and 6 had both a dog and a cat. How many children had neither
Gnesinka [82]

Answer:

7

Step-by-step explanation:

Although I don’t see that answer, with 53 children and 22 having a dog, 18 a cat, and 6 with both, you would think to subtract all three of those numbers with 53 to get the remaining with no dogs or cats, which results to 7
