This problem lends itself to the binomial probability approach.
Focus on students who are not secretly robots.
Then P(student is not a robot) = 2/6, or 1/3. Here n=6 and x=2.
Then the desired probability is binompdf(6,1/3, 2), which, by calculator, comes out to 0.329.
Hello,
The sequence is geometric of ratio -4.
Answer 2 and 4 are good. others false
The slope of cd is 2/5
the slope of ef is -4-y/10
the lines are parallel so the slopes are equal
-4-y/10= 2/5
-4-y=2/5x10=4
-y=4=4=8
y=-8
Answer:
2√2
Step-by-step explanation:
Given
g(x) = ✓(x - 4)
h(x) = 2x - 8
Now
g(h(10))
= g ( 2 * 10 - 8)
= g(20-8)
= g(12)
=✓(12 - 4)
= ✓8
=2√2
Hope it will help ✓
