Answers
Answer:
Step-by-step explanation:
No. of prize cards = 5
No. of blank cards = 20
Total cards = 5+20=25
We are given that a contestant is asked to choose a card at random.
Now we are supposed to find what is the probability that he won
Favorable events = Prize cards = 5
Total events = 25
So, the probability that he won
=
Hence the probability that he won is
The probability of winning is 1/5.
Given - Number of prize cards and blank cards
Find - Probability of winning
Solution - Total number of cards = number of prize cards + number of blank cards
Total number of cards = 5 + 20
Performing addition
Total number of cards = 25
Probability = number of favourable outcomes/total number of outcomes
Number of favourable outcomes = 5
Total number of outcomes = 25
Probability =
Performing division of numerator and denominator by 5.
Probability =
Hence, the probability of winning the game is 1/5.
