The probability that fewer than 4 of them are successful are 0.9527
<u>Explanation:</u>
Given:
number of trials, n = 6
p(successful) = 0.85
P(x >= 4) = ?
The problem can be solved using binomial probability formula.
P(x >= 4) = 1 - binomcdf(6,0.85,4) = 1 - 0.0473
= 0.9527
Therefore, the probability that fewer than 4 of them are successful are 0.9527
Answer:
40
Step-by-step explanation:
8 = x/5
x = 8*5
x = 40
There are 52 cards in a standard deck so that would be the whole in the part/whole equation so
i... There are 13 spade cards and then 3 other aces since there are 4 suits of cards so 16/52 or about 0.30769 or 30.8% rounded
ii....There are 2 reds of each card in a standard deck along with 2 blacks so there would be 2 red kings which would be a 2/52 chance or about 0.0384 or 3.8% rounded
iii.... There are 4 kings and 4 queens in each deck so (52-8)/52 which is a 44/52 chance, 0.8461 about, or 84.6% rounded
iv..., As I said in iii, there are 8 kings and queens so an 8/52 chance, about 0.1538, or 15.4% rounded
Answer: the third one down
26 miles times 5,280 feet
Step-by-step explanation:
Look at the units. Miles over miles will cancel, leaving feet... 1 mile is 5,280 feet, because a mile is bigger than a foot, and there are 5,280 feet per 1 mile.
