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
60min or 1 hour
Because 2km is equal to 2000m
Therefore you multiply 12 min by 5 (because 2000m x 5 is 10000m)

Answer:
Sampling bias
Step-by-step explanation:
Bias refers a prominent problem in statistical analysis whereby one or more analytical factor are favored than the other during an analysis which should be made random. The problem. With Graham's dissertation study is the fact that he failed to randomlyvplace his subjects or observation in the study groups, favoring a particular group with non random subset. When randomization is ejected or missing from an analysis or study, it becomes less and less representative. Here, allotting early Arrivals Into the treatment group has introduced a sampling bias as those who came later, this will also leads to less reproducibility of experiment.
