Hello!
You have to add how many trials he did
41 + 19 + 28 + 12 = 100
Now you look for the box that has 6 and tails
It has a 12 in it
You do 12/100
This can be reduced to 3/25
The answer is A
Hope this helps!
A. P[TTTTH] = .55^4*.45 = .0412
<span>b. P[HHHT] = .45^4*.55 = .0226 </span>
<span>c. 1/.45 = 2.222 </span>
<span>d. 1/.55 = 1.818</span>
I'M not sure sorry i just keep getting
1/4x
50k is the same as 50,000
73% = 73/100 = 0.73
Multiply 50,000 with 0.73
50,000 x 0.73 = 36500
You spend $36500.
Subtract 36500 from the total
50,000 - 36,500 = $13,500
$13,500 is the amount of money you have left.
hope this helps
