Total number of cards =18

Even numbers from 3 to 20 are 4, 6, 8, 10, 12, 14, 16, 18, 20 = 9 numbers

Probability that the number on the card taken out is an even number

42. Two coins are tossed simultaneously. Find the probability of getting exactly one head.

Answer:

Explaination:

When two coins are tossed simultaneously

Total number of outcomes = {HH, HT, TH, TT}

Total number of outcomes = 4

Favourable outcomes = {HT, TH} = 2

Probability of getting exactly one head = \(\frac{2}{4}=\frac{1}{2}\)

43. An unbiased die is thrown, what is the probability of getting an even number.

Answer:

Explaination:

Total outcomes = {1, 2, 3, 4, 5, 6}

Favourable outcomes = {2, 4, 6}

∴ Probability of getting an even number = \(\frac{3}{6}=\frac{1}{2}\)

44. If the probability of winning a game is 0.3, what is the probability of losing it?

Answer:

Explaination:

Probability of winning a game = 0.3

∴ Probability of losing the game

= 1 – Probability of winning the game

= 1 – 0.3 = 0.7

45. A man is known to speak truth 5 out of 7 times. He throws a die and a number other than 6 comes up. Find the probability that he reports it is a six.

Answer:

Explaination:

P(man will speak the truth) = \(\frac{5}{7}\)

∴ P(man will not speak the truth) = 1 – \(\frac{5}{7}=\frac{2}{7}\)

when a number other than 6 comes up the probability of man’s reporting it is a six the probability of man not speaking the truth \(\frac{5}{7}\)
