The probability that the sum of the two numbers Malik picks is less than 5, given that the first number is odd and less than 5 is 0.0494.
What is a probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about how probable an event is to happen, or its chance of happening.
Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.
Probability of an event P(E) = Number of favourable outcomes/Total number of outcomes.
Calculation for the given condition;
Either 1 or 3 must be present if a given integer is odd and smaller than 5.
The likelihood that it was picked from a set of nine numbers is (2/9).
The probability that the first integer is 1 is 50/50.
If it is and their combined number is less to 5, the second number will either be 1, 2, or 3.
The likelihood that it was picked out of the nine numbers is (3/9).
Additionally, there is a 50/50 probability that the first digit will be 3.
A second number is 1 if it is and the sum would be less than 5.
It was selected with a 1 in 9 chance of being one of the other 8 numbers.
The total probability is;
= (2/9) times [ (0.5 x 3/9) + (0.5 x 1/9) ]
= (2/9) times [ (1.5/9) + (0.5/9) ]
= (2/9) times [ 2/9 ] = 4/81
= 0.0494
Therefore, the probability that the sum of the two numbers malik picks is less than 5 is 0.0494.
