8_murik_8 [283]

Answer:

7 / 13

Step-by-step explanation:

The number of cards in a standard deck = 52

Number of red cards in a deck = 26

Number of queens in a deck = 4

Selecting a card at random ;

Probability of picking a red card ;

P(red card) = number of red cards / number of cards in deck

P(red card) = 26 / 52

P(queens card) = number of queens / number of cards in deck

P(queens card) = 4 / 52

Number of red queen cards = (red n queen) = 2

P(red or queens card) = P(red) + P(queens) - P(red n queen)

P(red or queens card) = 26/52 + 4/52 - 2/52

= (26 + 4 - 2) / 52

= 28 /52

= 7 / 13

\sf\huge\underline\red{SOLUTION:}

Use formula:

\sf{V = \pi(\frac{d}{2})^2h}

Solving for diameter:

\sf d = 2 \times  \sqrt{ \frac{V}{\pi h} }  \\ \sf = 2 \times   \sqrt{ \frac{40}{\pi \times 1800} } \approx0.16821 \\  = \sf \large\boxed{\sf{\green{d = 0.17}}}
