So the original price is "x".
the discounted price by 10% is P(x) = 0.9x.
the price minus a $150 coupon is C(x) = x - 150.
so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!! wait a minute!! you have a $150 coupon, and you can use that for the purchase, so you're really only getting out of your pocket 0.9x - 150, namely the discounted by 10% and then the saving from the coupon.
C( P(x) ) = P(x) - 150
C( P(x) ) = 0.9x - 150
Answer : 5/22
A deck of cards contains 6 black cards and 6 red cards. The first card drawn is not replaced before drawing the second card.
Total number of outcome of cards = 12
Probability( any event)= favorable outcomes divide by total number of outcomes
Probability of selecting black card =
The drawn card is not replaced . so 11 cards left . In that 11 cards, 5 black cards because one black card is already chosen
Probability of selecting another black card =
Probability of selecting a black card followed by another black card =
=
=
Answer: questions one and two
Step-by-step explanation:
Since we already know that the older child is a girl (a 100% chance to be a girl), there must be a 50% chance that the other child is a girl. Therefore, the probability that both children are girls is 50%.
Hope this helps!
The answer is 34%
30+33%=39.9
So round up two 34%
I hope that is right but I think the answer is 34%
