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
Answer:
The sum of the interior angles in a triangle is always 180. So, if two angles sum up to 136 degrees, the remaining angle must complement to 180, and it must be
180-136=44
degrees
Step-by-step explanation:
How are we supposed to answer this? there's no question... o_o
