Question

Examine each of the following statements and comment:
(i) If two coins are tossed at the same time, there are 3 possible outcomes – two heads, two tails, or one of each. Therefore, for each outcome, the probability of occurrence is 1/3.
(ii) If a die is thrown once, there are two possible outcomes – an odd number or an even number. Therefore, the probability of obtaining an odd number is � and the probability of obtaining an even number is 1/2.

Answer 1

Answer:

i) no the probability will be 1/4

ii) odd no. 3/6=1/2

Answer 2

(i) 1/4, 1/4, 1/2 ; (ii) 1/2

Step-by-step explanation:

(i) When two coins are tossed at the same time, there are 4 possible outcomes.

head tail

head head

tail tail

tail head

 So the probability of both heads or both tails is 1/4.

Probability of either head or tail is 1/2.

(ii) When a dice is thrown once, there are 6 possible outcomes. 3 outcomes for an odd number or 3 outcomes for an even number.

So probability of obtaining an odd number = probability of obtaining an even number = 3/6 = 1/2.
