If there is 2 field trips with 23 students and each student costs $5 dollars. So for the 1st trip it will be 23x$5
1st trip- $115
And on the second trip its the same because there is 23 students that cost 5 dollars so it will be 23x5
2nd trip- $115
To find out the total of both trips youd add 115+115/
In total, for both trips it will cost $230 dollars.
Answer:
a) P(2) = 0.2646
b) P(x > 2) = 0.5334
c) P( 2 <= x < = 5) = 0.7694
Step-by-step explanation:
n = 10
p = 0.27
q = 0.73
x = 10
P(x=0) = (10 C 0 )(0.27^0)(0.73^(10-0)) = 0.043
P(x=1) = (10 C 1 )(0.27^1)(0.73^(10-1)) = 0.159
P(x=2) = 0.2646
P(x=3) = 0.2609
P(x=4) = 0.1689
P(x=5) = 0.075
P(x=6) = 0.0231
P(x=7) = 0.0049
P(x=8) = 0.000677
P(x=9) = 0.0000557
P(x=10) =0.00000206
a) P(2) = 0.2646
b) P(x > 2) = P(3) + P(4) + P(5) + ... + P(10) = 0.5334
c) P( 2 <= x < = 5) = P(2) + P(3) + P(4) + P(5) = 0.7694
