A school has an equal number of boys and girls. You use a coin to simulate the first three students to arrive at school each day, where “heads” represents a boy and “tails” represents a girl. The table below shows a sample of 20 coin tosses

Find the experimental probability that the first three students to arrive at school are boys.
(1 point)
A.three over twenty
B.one-fifth
C.three-tenths
D.one-fourth
I think it's A am I right?
1. B
2. D
3. A
4. C

B D A C is 100% correct I have written out the answers below
1) 0.22
2)54
3)3/20
4)2/5
i got 100% with these answers
I got a 75% with Minion's answer
What is the experimental probability of rolling a 3?
A.0.11
B.0.22
C.0.30
D.0.27
================ 11/50 = 22/100 = .22
WRONG its
B

A
C
I did it and 2 was wrong.
i just have to say minion is wrong and that FellowConnexusUser is 100% correct.
Oh yeah just gotta 100% with B,D,A,C so thanks
Thx connexus user, idk if the answers change up for certain people, but I got 100% with ur answer
The answer is B. D. A. C. Don't listen to the others these are 100% correct. Minion is wrong.
Thanks Can you help me with some more questions please?
Thanks what's number one and four?
1: B
2: B
3: A
4: C
Thank you Fellowconnexus User 100%
Fellow connexus user is wrong, the right answers are

Is correct, I hope that helps someone <3
I counted 3 out of 20
Yes, you have it
Yeah what's number 1 and 4
1=0.22
2=35
3=3/20
4=2/5
For me, it was B A D C:
.22
54
3/20
2/5
This was right for me, maybe not for you, though.
