refer to the venn diagram to the right for events a and b in an equally likely sample space s. find the indicated probability. p(a∪b) p(a∪b)=□ (type a decimal.)

refer to the venn diagram to the right for events a and b in an equally likely sample space s. find the indicated probability. p(a∪b) p(a∪b)=□ (type a decimal.)

Answer

Explanation:

Step1: Calculate total number of elements in sample space

$40 + 10+30 + 20=100$

Step2: Calculate number of elements in $A\cup B$

$40+10 + 30=80$

Step3: Calculate $P(A\cup B)$

$P(A\cup B)=\frac{80}{100}=0.8$

Answer:

$0.8$
