Question

how do we find the probabilities?

Answer 1

$<b >$ We need to divide no. of outcomes by total no. of outcomes.
Probability is denoted by P.

For example, The total number of marbles in a bag is 25 and there are 10 green marbles and 15 white marbles.

To find the probability of green marbles,

P (green marbles) = Number of green marbles / Total number of marbles = 10 / 25 = 0.4

To find the probability of white marbles,

P(white marbles) = Number of white marbles / Total number of marbles
= 15/25 = 0.6

Hope you got it!

Answer 2

Number of favourable outcomes / Total number of possible outcomes of the experiment
