Frame 20 Probability questions on coins, dice and cards.
Answers
Answer:
Coins
When you toss a coin, you flip it up into the air in such a way that it is spinning rapidly while in flight. You then catch it and place it on the back of your hand. Being disc-shaped, it can have one of two faces uppermost. Conventionally, the two sides are known as "heads" (the portrait of the Queen) and "tails" (the other side). When we use coin tossing in probability examples, we make the assumption that heads and tails are equally likely, that is,
P(heads) = P(tails) = 1/2.
Dice
N.B. DIE is singular ("one die") and DICE is plural ("twelve dice").
A die is a solid cube, and so has six faces. The faces are marked with the numbers 1 to 6 (1 being opposite 6, 2 being opposite 5 and 3 being opposite 4). When the die is thrown on to a flat surface, it rolls and eventually comes to a stop. The number on the uppermost face is taken to be the result --- a random number between 1 and 6 inclusive. We generally assume that
P(1) = P(2) = P(3) = P(4) = P(5) = P(5) = 1/6.
