Answer:
1/16
Step-by-step explanation:
Possible outcomes when rolling a fair die = 1, 2, 3, 4, 5, 6 (i.e 6 possible outcomes)
Possible outcomes when rolling an even number = 2, 4, 6 (i.e 3 possible outcomes)
Hence P (rolling even number on 1 roll) = 3 / 6 = 1/2
P (Rolling 4 even numbers on 4 rolls) = (1/2)(1/2)(1/2)(1/2) = 1/16
Answer:
B. (-2,3)
Step-by-step explanation:
-3x+5y = 21
x=2y-8
Substitution
-3(2y-8)+5y =21
-6y+24+5y=21
-y+24=21
-y=-3
y=3
Plug-in other equation
2*3-8=x
6-8=x
x=-2
Yes, there is a 50% chance it will rain. This leaves the other 50% chance to be that it will not rain. This fills up 100% of the possibilities. It is only logical that it will either rain or it won't, there is no third option.
