Question

Numbers 1 to 12 are written on twelve separate cards (one number on each card), kept in a box and mixed well. One card is chosen from the box without looking at it. Find the probability of getting a card having a number greater than or equal to 7. *

1/2
1/3
4/5
1/6

Answer 1

Step-by-step explanation:

no. of cards greater than or equal to 7 are 7,8,9,10,11,12

total no of cards =12

probability of drawing a card greater than or equal to 7

= no of cards >=7/ total number of cards

=6/12 =1/2
