The total cost is 13.76, she has enough money. (accidentally posted the answer in the comments so ignore that)
Answer: I got 4x^2-12x+14 hope this helps :)
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
Use the Pythagorean theorem, a² + b² = c², where a and b are legs of the right triangle and c is the hypotenuse.
13 spades, 52 cards total
probability of drawing a single spade = 13/52 = 1/4
If we replace that card, then the probability of drawing of drawing a spade is still 1/4 as nothing has changed
Overall, the probability of getting two spades in a row is (1/4)*(1/4) = 1/16
note: the two events are independent because of the replacement happening
---------
The answer as a fraction is 1/16
As a decimal, that would be 0.0625 which converts to 6.25%
