Answers
Step-by-step explanation:
Given:-
17 cards numbered 1.2, 3,...,17 are put in a box and mixed thoroughly. One person draws a card from the box.
To find:-
Find the probability that the number on the card is odd.
Solution:-
Given that
Total number of cards = 17
Total number of all possible outcomes = 17
The sample space = {1,2,3,...,17}
The odd numbers are = 1,3,5,7,9,11,13,15,17
Number of favourable outcomes = 9
We know that
Probability of an event P (E) =
Number of favourable outcomes / Total number of all possible outcomes
Drawing a card from the box is an event then
Probability of getting an odd number = P(Odd)
= Number of favourable outcomes to odd number / Total number of all possible outcomes
=> P(Odd) = 9/17
Answer:-
The probability that the number on the card is ood number = 9/17
Used formula:-
- Probability of an event P (E) =
Number of favourable outcomes / Total number of all possible outcomes
Answer:
that will be 9/17
Step-by-step explanation:
favourable outcomes(total no. of odd no. cards) =9
total out come= 17
probability = 9/17
