For the last 2 questions,
1. 9/10
2. 7/12
Answer:
x=9
Step-by-step explanation:
First, distribute the 2 and each value in the parentheses.
2*x+2*5. This is the first half of the equation.
2*x+2*5= 3x+1 You can then simplify
2x+10=3x+1 Subtract 3x from both sides
(2x-3x)+10=(3x-3x[cancels out])+1
-x+10=1 Now subtract 10 from both sides
-x(10-10[cancels out to 0])=(1-10)
-x=-9 Since x is negative we need to solve for positive
x=9
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
