Answer: Intersection of A and B = 2
Step-by-step explanation:
Total cards = 52
Let A is the event of drawing a 6 from the deck, and B is the event of drawing a black playing card from the deck.
Total cards having 6 on them = 4
[There are 4 suits of two different colors red and black.]
Total black playing card =26
Intersection of A and B = Black cards having 6 = 2
hence, Intersection of A and B = 2
List the 2 steps to solve and the
solution.
Answer:
(This way you have to solve for x)
way 1
step 1: 2x+=5
step 2: 2x=5-1
step 3: 2x=4
answer x=2
(This way you have to solve by rewriting in standard form)
way 2
step 1: 2x+1=5
step 2: 2x=5-1
step 3: 2x=4
answer x=2
