Question

Find the probability of selecting an even number from the cards numbered from 1 to 100.​

Answer 1

even number from 1 to 100 are

2,4,6,8,10,12,14,116,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60,62,64,66,68,70,72,74,76,78,80,82,84,86.88.90.92,94,96,98,

100.

So, there are total 50 even numbers between 1 and 100.

Probability = Total outcomes/ Possible outcomes

=50/100

=1/2

Answer 2

To Find :- The probability of selecting an even number from the cards numbered from 1 to 100.

Solution :-

→ Total number of cards = From 1 to 100 = 100

So,

→ Total number of possible outcomes = 100

now,

→ Total number of even numbered cards = 100/2 = 50

{ There are 50 odd numbers and 50 even numbers from 1 to 100. }

then,

→ Total number of favourable outcomes = 50

therefore,

→ Required probability = Total number of favourable outcomes / Total number of possible outcomes

→ Required probability = 50/100

→ Required probability = 1/2 (Ans.)

Hence, the probability of selecting an even number from the cards numbered from 1 to 100 is equal to 1/2 .
