a) Probability that all 5 numbers match is computed here
as:
= 1 / Total number of ways to select 5 numbers from 50 numbers
Therefore 1/ 2118760 is the required probability here.
b) Probability that three of the 5 numbers match is computed here as:
= Number of ways to choose 3 numbers from the 5 numbers selected * Number of ways to select rest 2 numbers from the remaining 45 numbers / Total ways to select 5 numbers from 50 numbers
Therefore 0.0047 is the required probability here.
