Answer:
The probability of seeing both = 0.32
Step-by-step explanation:
<u>Step:-(i)</u>
Given data the probability that you see a butterfly during a nature center tour is 80%
Let 'B' be the event of butterfly during a nature center tour
The probability that you see a butterfly during a nature center tour is 80%
P(B) = 80% = 0.80
Given data the probability that you see a turtle is 40%
Let 'T' be the event of turtle a nature center tour
P(T) = 40% = 0.40
<u>Step:-(ii)</u>
<u>Independent events </u>
If the occurrence of the event B is not effected by the occurrence or non-occurrence of the event 'A' , then the event 'B' is said to be independent of 'A'
If A and B are independent events then
P(A ∩B) =P(A) P(B)
now the given data the butterfly and turtle are independent events
probability of seeing both
P(B∩T) = P(B).P(T)
= 0.80 × 0.40
= 0.32
Answer:
x = 3 and y = 1
Step-by-step explanation:
The given equations are :
6x + 14y = 32 ...(1)
6x - 14y = 4 .....(2)
Add equation (1) and (2) :
6x + 14y + 6x - 14y = 32 + 4
12x = 36
x = 3
Put the value of x in equation (1)
6(3) + 14y = 32
18 + 14y = 32
14y = 32-18
14y = 14
y = 1
Hence, the value of x is 3 and y is 1.
Answer:
Step-by-step explanation:
Step 1: Convert into improper fractions
Step 2: Find least common denominator and find equivalent fractions
Step 3 : Do the required operation
Least common denominator of 2 , 4 = 4
4x3=12/2=6
Your answer is 6.
