By addition theorem of probability,
P(AUB) = P(A) + P(B) -P(A∩B)
or
P(A or B) = P(A) +P(B) - P(A and B)
P(A or B) = 0.7 + 0.4 - 0.3 = 0.8
Therefore, the probability that randomly selected person likes pizza or burger is 0.8

Step-by-step explanation:
The equation given is ;
y=√-x-3----------------------square left side to eliminate the root
y²= -x-3
graph y²= -x-3 on a graph tool
1. 12a+6=12a+6
2. 12a+6=12a+2
3. 12a+6=4a+6
4. 12a+6=7a+5
Answer:
180.8 or just round to 181
Step-by-step explanation:
Answer:
1/12 or 8.33% is the probability
Step-by-step explanation:
Assuming the number cube has 6 sides there is 1/6 chance of getting a 3 and a 1/2 chance of getting tails when flipping a coin. Multiplying 1/6 by 2 to get 1/12.
