Of those mountain climbers who attempt Mt. McKinley, only 65% reach the summit. In random sample of 11 mountain climbers who attempt to climb Mt. KcKinley, what is the probability of 11 mountain climbers reaching the summit? Round to 4 decimal values

Probability that all 11 sampled mountain climbers make it to the top of Mt. McKinley = 0.088

Step-by-step explanation:

This is a binomial distribution problem

Binomial distribution function is represented by

P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ

n = total number of sample spaces = number of mountain climbers sampled = 11

x = Number of successes required = 11

p = probability of success = Probability that one mountain climbers makes it the top of Mt. McKinley = 0.65

q = probability of failure = 1 - p = 0.35

P(X = 11) = ¹¹C₁₁ (0.65)¹¹ (0.35)¹¹⁻¹¹

P(X=11) = 0.00875078317 = 0.0088 to 4 d.p

Hope this Helps!!!

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2
