The probability of the friend completing the new level in her first try is 22.5%
<h3>What is probability?</h3>
This is a concept that is used to talk about the likelihood or the chances of an event occuring.
For the digit 8, the frequency is 7
For the digit 9, the frequency is 11
The total number of frequencies is given as
10 + 9 + 6+ 7 + 8 + 12 + 4 + 6 + 7 + 11 = 80
7 + 11 = 18
Probability = 18/80
= 0.225 x 100
= 22.5%

Erin scored 1 of 2, or in fraction form: 1/2
Lauren scored 6 of 8, or in fraction form: 6/8
Find common denominators. multiply 4 to numerator and denominator of 1/2
(1/2) x (4/4) = 4/8
4/8 > 6/8
Lauren was more successful
hope this helps
Question
what's the answer to this

Answer:
<h2>
4</h2>
Step-by-step explanation:
4 (w+1)-4w =
4w + 4 - 4w =
4
Square root of 6 is 2.44 so place the dot at the the 2.4 place.
Binomial distribution because:
Trials are Bernoulli (affected or not)
Probability is known (p=0.05) and remains constant for all trials.
Number of trials is known (n=6).
P(x)=C(n,x)p^x*(1-p)^(n-x)
x=0 =>
P(0)=C(6,0)(0.05^0)(0.95^6)
=0.7351.... (approximately)
