Consider the experiment of tossing a coin three times. How many experimental outcomes exist? Let x denote the number of heads occurring on three coin tosses. Show the value the random variable would have for each of the experimental outcomes. Outcome Value of x (Head, Tail, Head) (Head, Head, Head) (Head, Tail, Tail) (Tail, Head, Head) (Tail, Head, Tail) (Tail, Tail, Tail) (Tail, Tail, Head) (Head, Head, Tail) Is this random variable discrete or continuous?

a) 8 b) 1, 3, 1, 2,1,0,1,2  c) discrete random variable

Step-by-step explanation:

a) possible outcomes: (Head, head, head), (head, head, tail), (head, tail, head), (head, tail, tail), (tail, head, head),(tail, head, tail), (tail, tail, head), (tail, tail, tail)

b) see the attachment. The table is to be filled with values of x

c) since the number of times head occurs is a discrete number, x is a discrete random variable

25% is the answer

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
