(8)=ones place
(1)0=tens place
(1)00=hundreds place
(9)000=thousands place
The "1" beside the 8, is the tenths spot so you would round that part of the number.
Therefore the answer would be:
9120
Round and then see what the number you have too add, subtract , multiply, and divide and then you would find the answer
Let A= the sky is red at night
let B= the weather will be nice the next day
Since this is based on Conditional Probability,
P(B|A)
This is read: The probability that the weather iss nice the next day GIVEN the sky is red at night.
