Answer:
a) 0.145
b) 0.013
c) 0.783
d) 0.586
Step-by-step explanation:
a) there are always 52 cards in total, 13 hearts
Pa = 39/52 × 38/51 × 13/50 = 19266/132600 = 257/1700 =0.145
b) there are always 13 diamonds in a complete card
Pb = 13/52 × 12/51× 11/50 = 11/850 = 0.013
c) there are always 4 aces, and 48 that are not aces
Pc = 48/52 × 47/51 × 46/50 = 4324/5525 = 0.783
d) there are 13 hearts,to get at least one heart we have.
Pd = 1 - p
Where p is the probability of no hearts
p = 39/52 × 38/51 × 37/50 = 703/1700 = 0.414
Pd = 1 - 0.414
Pd = 0.586
12 of the cookies are chocolate chip. 18 divided by 3 is 6. 2 multiplied by 6 is 12.
I can't see the negative balance that is mentioned.
But for example it it was a -$22.00 then you would just subtract the $22.00 from $47.00.
$47.00
-$22.00
-------------
$25.00

Answer: 1/4
Step-by-step explanation:
1/4 of 9 is 3, so 9 * 1/4 equals 12. 3/4 * 1/4 = 1, so x stays the same.
3/4x=9
*1/4
x = 12
