The binomial cumulative probability with p=0.5 for 3+ successes is as follows:

for p=0.5 (50% success rate) it becomes:

the probability is 0.65625, or about 66%
Answer:
This is 0.14 to the nearest hundredth
Step-by-step explanation:
Firstly we list the parameters;
Drive to school = 40
Take the bus = 50
Walk = 10
Sophomore = 30
Junior = 35
Senior = 35
Total number of students in sample is 100
Let W be the event that a student walked to school
So P(w) = 10/100 = 0.1
Let S be the event that a student is a senior
P(S) = 35/100 = 0.35
The probability we want to calculate can be said to be;
Probability that a student walked to school given that he is a senior
This can be represented and calculated as follows;
P( w| s) = P( w n s) / P(s)
w n s is the probability that a student walked to school and he is a senior
We need to know the number of seniors who walked to school
From the table, this is 5/100 = 0.05
So the Conditional probability is as follows;
P(W | S ) = 0.05/0.35 = 0.1429
To the nearest hundredth, that is 0.14
Answer:
Step-by-step explanation:
25/3 3 goes into 25 8 times with 1 left over. 8 1/3 is your answer
3/4<span> / 2</span>
= 6/8 / 2
= 3/8
You need 3/8 cups of flour
