Answer:
299.03
Step-by-step explanation:
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
X=0 (4×0)+3=3 that I think is the absolute value
Answer:
p =11, q = 3
Step-by-step explanation:
p-q=8
2p-q =19
Multiply the first equation by -1
-p+q = -8
Add this to the second equation
-p+q = -8
2p-q =19
------------------
p = 11
Now we can find q
p -q = 8
11 -q = 8
Subtract 11 from each side
11-11-q = 8-11
-q = -3
q =3
