P(x) = C(5,X) *0.3^x *(1-0.3)^5-x
x = 0
P(0) = C(5,0) *0.3^0*0.7^5
= 5 *1 *0.16807
= 0.84035 = 84.0%
I'm sorry, I don't see the question. Could you please retake the photo in better quality so I could answer it? Thanks!
$48 because you have to find the totals for both then subtract
84 cm because you HAVE to add them together.
