Answer:
c=56.3
Step-by-step explanation:
Sorry for the bad writing and diagram haha
It is given in the question that "An athlete complete a race in 55.72 seconds."
The digit at the tens place is 5 and the digit at the ones place is 5 too .
So if compare the digit at the tens place and the digit at the ones place, we will get that both are equal .
And that's the required comparison .
No need for the diagram (though it helps)
P(AUB) = P(A) + P(B) - P(A and B),
P(A) = 0.61 - 0.41 + 0.18 = 0.38
So, D!!
