If a and b are mutually exclusive events, with p(a) = 0.19 and p(b) = 0.27, what is p(a or b)?
a) 0.05

b) 0.40
c) 0.42
d) 0.46

The correct option is D. 0.46

Step-by-step explanation:

P(A) = 0.19

P(B) = 0.27

Now, Both the events A and B are given to be mutually exclusive

⇒ P(A ∩ B) = 0

Now, We need to calculate P(A or B)

⇒ P(A or B) = P(A) + P(B)

⇒ P(A or B) = 0.19 + 0.27

⇒ P(A or B) = 0.46

Hence, The correct option is D. 0.46

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

answer: 30
