Q1: A die is thrown once. Find the probability of getting (a) an even number, (b) a number greater than 4.
When a die is thrown once, possible outcomes: {1, 2, 3, 4, 5, 6}
Total possible outcomes = 6
(a) Find probability of getting an even number:
Favourable outcomes: {2, 4, 6}
Number of favourable outcomes = 3
P(even) = 3/6 = 1/2
(b) Find probability of getting a number greater than 4:
Favourable outc...
Q2: Two coins are tossed simultaneously. Find the probability of getting (a) both heads, (b) at least one tail.
When two coins are tossed, possible outcomes: {HH, HT, TH, TT}
Total possible outcomes = 4
(a) Find probability of both heads:
Favourable outcomes: {HH}
Number of favourable outcomes = 1
P(both heads) = 1/4
(b) Find probability of at least one tail:
Favourable outcomes: {HT, TH, TT}
Number of favo...
Q3: A card is drawn from a standard deck of 52 cards. Find the probability of drawing (a) a king, (b) a red card, (c) a diamond.
A standard deck has 52 cards with 4 kings, 26 red cards, and 13 diamonds.
(a) Probability of drawing a king:
Number of kings = 4
P(king) = 4/52 = 1/13
(b) Probability of drawing a red card:
Number of red cards = 26
P(red) = 26/52 = 1/2
(c) Probability of drawing a diamond:
Number of diamonds = 13...
