hey mate!
here is your answer:
total number of outcomes=100
1.number of favourable outcomes=50
probability =50/100=1/2
2.number of favourable outcomes=7
probability =7/100
3.number of favourable outcomes=10
probability =10/100=1/10
4.number of favourable outcomes=8
probability =8/100=2/25
hope it helped ^_^
vivans7555:
Can you tell me what are the perfect square numbers between 1 and 100.
perfect square numbers between 1 and 100= 4,9,16,25,36,49,64,81
So in your answer did you take 4,9,16,25,36,49,64,81 and not 1 and 100.

Answer:
Step-by-step explanation:
1) no. Of even integers are 50
So probability becomes 1/2
2)no. Of integers which are multiple
of 13 and less than 100 are 6
So probability becomes 3/50
3) no. Of integers which are perfect
square and less than 100 are 9
So probability becomes 9/100
4) no. Of integers which are prime
number and less than 20 are 8
So probability becomes 2/25
Pls mark as brainliest brother
Buddy there are 10 favorable outcomes in of perfect square numbers and u took only 9
Less than to 9 hi hai
There are 10 perfect squares buddy
