Answer:
E= 3/20
Step-by-step explanation:
Number of blue disk= 3
Number of green disk= 3
Number of orange disk= 4
Total number of disk = 3+3+34
= 10
Let B represent blue disk
Let G represent green disk
Let O represent orange disk
If three disk are selected at random, the possible outcome of one green disk and two orange disks are
OOG, OGO, GOO
Pr(OOG) = Pr(O1) * Pr(O2) * Pr(G3)
= 4/10 * 3/9 * 3/8
= 36/720
= 1/20
Pr(OGO) = Pr(O1) * Pr(G2) * Pr(O3)
= 4/10 * 3/9 * 3/8
= 36/720
= 1/20
Pr(GOOG) = Pr(G1) * Pr(O2) * Pr(O3)
= 4/10 * 4/9 * 3/8
= 36/720
= 1/20
Pr(total) = Pr(OOG) + Pr(OGO) + Pr(GOO)
= 1/20 + 1/20 + 1/20
= 3/20
Answer:
w ≤ 2200
Step-by-step explanation:
If a lift can lift a maximum weight of 2200pounds,<u> this means that the lift can not life a weight greater than 2200pounds.</u> For the expression needed, the inequality sign to use will be a less than or equal to sign( ≤ ).
Hence the requires inequality expression will be w ≤ 2200
Answer:
y = 3x + 4
Step-by-step explanation:
3x would be the number of people that show up to the party times the number of pizza's needed plus the 4 she already ordered
C is the answer by using distributive property
563*(10*10*10) that's you scientific notation
