Answer:
The probabilty of having at least one pink bulb if 4 bulbs are purchased is 13%.
Step-by-step explanation:
The proportion of pink bulbs is p=0.4.
If X is the amount of pink bulbs in a group of 4 bulbs, we can model this as a binomial distribution problem.
The probability that at least one of the bulbs is pink is P(X≥1)
The probabilty of having at least one pink bulb if 4 bulbs are purchased is 13%.
A=1/2 (b1+b 2)(h) is the area of a trapezoid
One day = 2 hours
6 days = 2 * 6 = 12 hours
You have to multiply hours he plays per one day with 6 days.

Answer:
0.5
Step-by-step explanation:
Circumference of a circle = 2πr.
Given, circumference = 3.14 meters.
Therefore,
2πr = Circumference of a circle
or, 2πr = 3.14.
or, 2 × 3.14r = 3.14,[Putting the value of pi (π) = 3.14].
or, 6.28r = 3.14.
or, r = 3.14/6.28.
or, r = 0.5.
