The correct answer is D) 1/52

You are trying to pick a 5 of diamonds at "random".

This doesn't mean in a row, or any other lucky pull, just at random.

This means out of the 51 other cards, you want know the probability of picking this specific card.

This means out of 52 cards, the chances of you picking a 5 of diamonds is 1/52.

Express 0.003597 to three significant figures

coldgirl [10]

Answer:

0.00360.

Step-by-step explanation:

Leading zeros in a number are not significant, so your number has four significant figures.

You must drop the 7 from 0.003597.

Since 7 is greater than 5, you must add 1 to the 9

$\begin{array}{r|l}1& \\0.00359 &\text{7}\!\!\!\!\diagup \\\mathbf{0.00360} & \\\end{array}$
