Aroom has an area of 60 sq meters and a perimeter of 32 meters. what is the length and width

1- Answer B

2- Answer B

1-

Probability of getting a head = .5

Probability of getting a tail = .5

possible outcomes of getting at least one tail = HT, TT, TT

Probability in each of the above cases = .5*.5 +  .5*.5 +  .5*.5 = .75

This will be theoretical probability = .75

as per the question , experimental probability of getting at least one tail =

counting number of outcomes of(HT,TH,TT) ÷ total number of outcomes

experimental probability = (22+34+16) ÷ 100 = .72

So, theoretical probability is 3% greater than experimental probability

You can win only 15 % times.

so, out of 20 games, you can win = 15 % of 20 = 3

so total number of times you can win = 3 times
