The P(draw a black card) is 3/10.

<u>Step-by-step explanation:</u>

It is given that the deck contains 3 black cards and 7 red cards.

Therefore, the total number of cards in the deck = 7 red + 3 black = 10 cards.

Now, we need to find the possible outcomes of getting a black card. So, the number of black cards in the deck = 3 black cards.

<u>The formula to find the probability is given by :</u>

Probability = Number of required event / Total number of outcomes.

Here, the required event is getting a black card out of 10 cards in the deck.

  • The number of required event is 3.
  • The total number of outcomes is 10.

Probability (to draw black card) = 3/10.

I’m not *completely* sure if this would be right, but it could possibly be:
160
how i got this:
20 = 150
/(divide) 150
0.13(recurring) = 1
x1200
160 = 1200

Joan needs to estimate the size of her bedroom so that she can buy enough paint to cover the walls. Two of the walls measure 2.8
labwork [276]

The total area of the room is 37.6376 and the no. of cans required to paint the wall is 3 cans.

The measurement of two of the walls is 2.86 metres and 3.16 metre

Area of the two walls = 2(length x breadth)

Area = 2(2.86 x 3.16) = 18.0752 m²

The measurement of the other two walls is 2.86 metres and 3.42 metres

Area of the two walls = 2(length × breadth)

Area = 2(2.86 × 3.42) = 19.5624 m²

Total area = 18.0752 + 19.5624 = 37.6376 m²

If one can of paint can cover 15 m², the no. of cans required to paint the bedroom will be

No. of cans = Total area/Area covered by one can of paint

No. of cans = 37.6376/15 = 2.5091 = 3 cans (approx.)
