Answer:
0.4
Step-by-step explanation:
Given
60 % wear neither ring nor a necklace
20 % wear a ring
30 % wear necklace
This question can be Solved by using Venn diagram
If one person is choosen randomly among the given student the probability that this student is wearing a ring or necklace is


The sum of probabilty is equal to 1 because it completes the set
Therefore the required probabilty is 0.4
Absolute value cannot be less than 0

Answer:
9
Step-by-step explanation:
So the greatest 2 digit number is 99 and the greatest 3 digit number is 999
So find the hcf ( highest common factor ) of 99 and 999.
Factors of 99 : 1, 3, 9, 11, 33, 99
Factors of 999 : 1, 3, 9, 27, 37, 111, 333, 999
Common factors : 1, 3, 9
Hcf : 9
