Answer:
a.) Digits on the 5 cards are 1,2,3,4,5. You pick one card. You win if you pick a card having an even number.
b) Digits on the 5 cards are 1,2,3,4,5. You pick two cards. You win if you pick fist the card having number 5 and then the card having number 4.
Step-by-step explanation:
a) The probability of picking an even number is:
picking a card with even numbers (picking 2 or 4) / all cards (1,2,3,4,5)
b) Probability of picking the card having 5 first
Then the probability of picking the card having number 4 from the remaining 4 cards:
<em>Combined probability</em>, that is picking first number 5 and then number 4 is
Answer:
x = 4
Step-by-step explanation:
13x=32+5x

13x-5x=32+5x-5x
8x = 32
Divide each side by 8
8x/8 = 32/8
x = 4

Answer:
5 is NOT a solution to the equation.
t = 6
Step-by-step explanation:
Step 1: Write out equation
2t - 1 = 11
Step 2: Add 1 to both sides
2t = 12
Step 3: Divide both sides by 2
t = 6
