Dice have 6 numbers on it, so probability of getting one number is \\(1 \\over 6\\).

Probability of an event = \\(\\frac{Number of outcomes that make an event }{Total number of outcomes of the experiment}\\)

Number of outcomes of exactly three heads is = 1

Total outcomes = 8

Probability = \\(\\frac{Number of outcomes that make an event}{Total number of outcomes of the experiment}\\)

Probability = \\(\\frac{Number of outcomes that make an event}{Total number of outcomes of the experiment}\\)

Probability = \\(\\frac{Number of outcomes that make an event}{Total number of outcomes of the experiment}\\)

A die has six sides each consisting numbers from 1 to 6, i.e. {1, 2, 3, 4, 5, 6}.

Probability of an event = \\(\\frac{Number of outcomes that make an event}{Total number of outcomes of the experiment }\\)

Total number of marble = 14

Number of grey marbles = 7

Probability = \\(\\frac{Number of outcomes that make an event}{Total number of outcomes of the experiment}\\)
