Number of Elements in Union of Two Sets A and B Solution

Follow our step by step solution on how to calculate Number of Elements in Union of Two Sets A and B?

FIRST Step Consider the formula
n(A∪B)=n(A)+n(B)-n(A∩B)
Next Step Substitute values of Variables
∴ n(A∪B)=10+15-6
Next Step Prepare to Evaluate
∴ n(A∪B)=10+15-6
LAST Step Evaluate
∴n(A∪B)=19
