Sagot :
0.6 + 0.7- 0.8
solve that for pepperoni and olives
0.8= 1.3 - pepperoni and olives
A.K.A - 1.3 - 0.8 = 0.5
solve that for pepperoni and olives
0.8= 1.3 - pepperoni and olives
A.K.A - 1.3 - 0.8 = 0.5
Answer: 0.5
Step-by-step explanation:
Given: P(pepperoni) = 0.7
P(olives) = 0.6
P(pepperoni or olives) = 0.8
We know that for any events A and B , the probability of getting A and B is given by :-
[tex]\text{P(A and B)= P(A)+P(B)-P(A or B)}[/tex]
Therefore, we have
[tex]\text{P(pepperoni and olives)=P(pepperoni) +P(olives)-P(pepperoni or olives) }\\\\\Rightarrow\ \text{P(pepperoni and olives)}=0.7+0.6-0.8\\\\\Rightarrow\ \text{P(pepperoni and olives)}=0.5[/tex]
