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
Answer:
You mean just add them together?
Step-by-step explanation:
12.25 pounds
Answer: 13.74
Step-by-step explanation:
to find out the total cost we will:
13.09*(5/100)=0.65
13.06+0.65(tax)=13.74
So you have to add all the fractions together and then divide by five. When dealing with mixed fractions i like to add the whole numbers first, then add the fractions:
4 2/3, 1 1/4, 1 1/3, 3/4
the whole numbers: 4 + 1 + 1 = 6
then we are left with 2/3, 1/4, 1/3, 3/4
add the ones with common denominators together to make it easiest: 2/3 + 1/3 = 3/3 = 1 (another whole number! add it to 6 to get 7)
now we are left with 1/4 + 3/4 = 4/4 = 1 (another whole number! add it to 7 to get 8)
Now we know there are 8 cups of trail mix all together divide it by 5 friends and you get 8/5. 5 goes into 8 once with three left over so you get 1 3/5 cups per friend.
