Linda is playing a game where she is trying to draw a diamond from a standard deck of cards. If she doesn't get a diamond, she r
atroni [7]

Answer:

The answer would be 0.2%

Step-by-step explanation:

There's 52 cards in a standard deck of cards and a set of 4 for each different symbol. 100% of the deck would be 52 cards and each deck has 4 suits and each suite has 13 cards and 75% of the cards aren't the diamond Linda is looking for so it would be a slim to none chance on pulling a diamond out of the deck and shuffling the deck each time makes it worse so it gives her like a 0.2% chance of pulling a diamond.

Hope this helps :))

fenix001 [56]

Answer:

Yellow Bin

Step-by-step explanation:

<u>Yellow Bin</u>

Length = 11.4 inches,

Width = 4.2 inches,

Height =  \frac{8}{3}

Volume of the yellow bin=LWH=11.4 X 4.2 X \frac{8}{3}=127.68 \:cubic \:inches

<u>Red Bin</u>

Length = 9 inches,

Width = 5.45 inches,

Height =  \frac{11}{5}

Volume of the red bin=LWH=9X 5.45 X \frac{11}{5}=107.91 \:cubic \:inches

The yellow bin has a greater volume since 127.68 is greater than 107.91.
