Answer:
2/13
Step-by-step explanation:
For a deck of card
Total cards = 52
Total spade = 4
Total diamond = 4
pr(drawing a spade) = number of spade/total cards
pr(drawing a spade) = 4/52 = 1/13
pr(drawing a diamond) = 4/52 = 1/13
Pr(diamond or a spade) = 1/13 + 1/13 = 2/13
Rain : sunny : overcast
7:11:3
7x + 11x + 3x = 366
21x = 366
x = 366/21
x = 17.43
7(17.43) = 122.01 days rain
11(17.43) = 191.73 days sunny
3(17.43) = 52.29 days overcast
Wouldn’t the answer be 8 and 3
Chair=4x
lamp=x
table=4x-23
4x+x+4x-23=562
9x=585
x=585/9
x=65
4x=260
4x-23=237
