Answer:
1 /4
Step-by-step explanation:
Multiples of 5 = (5, 10, 15, 20, 25, 30, 35, 40, 45)
Numbers on card : (20,21,22,23,24,25,26,27,28)
Number on first card = 22
To have a sum which is a multiple of 5 ; number on second card must be either :
23 or 28
22 + 23 = 45
22 + 28 = 50
Since only 2 of the cards will. Result in a sum which is a multiple of 5
Required outcome = 2
Total possible outcomes = (9 - 1) = 8
Probability = required outcome / Total possible outcomes
= 2 / 8
= 1 /4
