Are the outcomes of every experiment equally likely

A die has six faces numbered from 1 to 6. It is rolled and the number on the top face is noted. When this is treated as a random trial. a) What are the possible outcomes ? b)Are they equally likely? Why? c) Find the probability of a composite number turning up on the top face.

Which of the following experiments have equally likely outcomes? Explain. A baby is bom. It is a boy or a girl.

Which of the following experiments have equally likely outcomes? Explain. A driver attempts to start a car. The car starts or does not start.

Which of the following experiments have equally likely outcomes? Explain. A trial is made to answer a true false question. The answer is right or wrong.

Which of the following experiments have equally likely outcomes? Explain. A player attempts to shoot a basketball. She /He shoots or misses the shot.

Outcomes of which of the following experiments are equally likely? 1. Getting a digit 1, 2, 3, 4, 5 or 6 when a die is rolled. Selecting a different colour ball from a bag of 5 red balls, 4 blue balls and 1 black ball. Winning in a game of carrom. Units place of a two digit number selected may be 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9. Selecting a different colour ball from a bag of 10 red balls, 10 blue balls and 10 black balls. Raining on a particular day of July

A bag contains five green marbles, three blue marbles, two red marbles, and two yellow marbles. One marble is drawn out randomly. a) Are the four different colour outcomes equally likely? Explain. b) Find the probability of drawing each colour marble i.e. , P(green), P(blue), P(red) and P(yellow) c) Find the sum of their probabilities.

Two biased dice are thrown together. For the first dice P(6) = (1)/(2) , the other scores being equally likely while for the second dice, P(1) = (2)/(5) and the other scores are equally likely. Find the probability distribution of 'the number of ones seen'.
