Consider the following information about spyder screening:
The probability of spyder hit chances are .01 .
If spyder is hit, T360 giving hit rating .80 .
If spyder is not hit, T360 probability incorrectly recognizing it as hit is .10

The conditional probability for T360 hit rating to spyder movie is _ out of 1,000. (Round to the nearest whole number)
