Answer:
0.01024
Step-by-step explanation:
Assume marking was done at random : Hence, each of the 5 time slots have equal Chamves of being marked ;
Number of time slots, n = 5
Required to mark, number of preferred timeslot x = 2
P(x) = 2 /5 = 0.4
Probability of 0.4 that an interviewee gets one of his preferred timeslot.
Probability that each of the 5 interviewees gets one of their preferred time slots :
Using the multiplication rule of independence :
0.4 * 0.4 * 0.4 * 0.4 * 0.4 = 0.4^5 = 0.01024
0.01024 * 100% = 1.024%
9^(6x)=3^(2x+4) I assume this is what you meant...
since 9=3^2
3^2^(6x)=3^(2x+4)
and since (a^b)^c=a^(bc)
3^(12x)=3^(2x+4)
so if a^b=a^c then b=c so
12x=2x+4
10x=4
x=0.4
