Answer:
3.5m
Step-by-step explanation:
Multiply both values by 7 to find that 7in=3.5m
315% is roughly 0.0382 of 82.53.
On the other hand, 315% of 82.53 is 259.9695 .
3/20 is 15% so that's bigger
Bruno had 10 bills for each if you don't count the 2 more $20 bills. If you want a complete number, bruno had 12 $20 dollar bills and 10 $10 bills
Use binomial distribution, with p=0.20, n=20, x=3
P(X=x)=C(n,x)p^x (1-p)^(n-x)
P(X>=3)
=1-(P(X=0)+P(X=1)+P(X=2))
=1-(C(20,0)0.2^0 (0.8)^(20-0)+C(20,1)0.2^1 (0.8)^(20-1)+C(20,2)0.2^2 (0.8)^(20-2))
=1-(0.0115292+0.057646+0.136909)
=1-0.206085
=0.793915
