<span>The <u>correct answer</u> is:

0.06.

Explanation<span>:

The probabilities of the first block having an error and the second block having an error are independent; one block having an error does not affect the probability of the second block having an error.

Since they are independent, to find the probability of both occurring, we simply multiply the probabilities:

0.2(0.3) = 0.06.</span></span>

To work out the probability of both errors occuring, simply multiply the probability of the first error by the probability of the second error. Therefore the probability of both errors occurring is 0.2 * 0.3  =  0.06.

I believe A and B are the ones. As for explaining? hmm. I would honestly say that any number to the right of a number is a tenth of the place above it. But then again, it's optional to explain ;P

X = 61 degrees.
Find the number of degrees in a pentagon by using the following formula:
(number of sides - 2)180 = 540.
There are 540 degrees in a pentagon.
Since we know four of the angles, we can subtract them from 540 to get the fifth angle.
540-138-144-107-90 = 61

Hope this helped =)
