Answer:
P(A or B) = 3/5
Explanation:
An independent event is an event that has no connection to another event's chances of happening. For A and B to be an independent event;
P(A or B) = P(A) + P(B)
Given the following parameters
P(A) = 1/5
P(B) = 2/5
Substituting the given parameters into the formula:
P(A or B) = 1/5 + 2/5
P(A or B) = 3/5
Hence the value of P(A or B) is 3/5
Sorry i only know questions one and two but
for question one 4/10 and 40% (i just converted the fraction to a decimal)
same for question two but its 6/10 and 60%
there are 10 letters in courageous
Answer:
A. 5 < AC < 10
Step-by-step explanation:
If ∆ABC is a right angled triangle, we use the Pythagoras formula:
c² = a² + b²
Where c = longest side
When given sides AB, AC and BC, the formula becomes:
AB² = AC² + BC²
Where AB = Longest side
In the question,
AB = 10 and BC = 5.
10² = AC² + 5²
AC² = 10² - 5²
AC² = 100 - 25
AC² = 75
AC = √75
AC = 8.6602540378
Therefore, the expression that is always true = A. 5 < AC < 10
Answer:
0.6443
Step-by-step explanation:
Given the that:
P(Z < 0.37) ; using a standard normal distribution :
The probability can be obtained using several methods :
Using a standard normal distribution table ;
P(Z < 0.37) = obtain the value at the intersection where 0.3 is on the vertical axis and 0.07 on the horizontal axis of the Z distribution table
Hence,
P(Z < 0.37) = 0.6443

i hope that helps with you’re expression
