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: -1 and 5.
Step-by-step explanation:
x - 4x = 5 : Move the constant to the left.
x^2 - 4x - 5 = 0 : Rewrite the expression.
x^2 + x - 5x - 5 = 0 : Factor the expressions.
x(x+1) - 5(x+1) = 0 : Factor the expression.
(x+1)(x-5) = 0 : Seperate into possible cases.
x + 1 = 0, x - 5 = 0 : Solve the equations.
x = -1, x = 5 : The equation has 2 solutions.
