Answer:
Determine AC with the pythagorean theorem, then you can find CD by subtracting AD.
with DC and BC, you can find BD. again, with the pythagorean theorem
Answer:
The probability that there will be more than one Phillips head screw = 0.1803 .
Step-by-step explanation:
We are given that there are 11 two-inch screws in a box of which 4 have a Phillips head and 7 have a regular head.
We are selecting 3 screws randomly from the box with replacement, so the probability that there will be more than one Phillips head screw is given by :
- <em>Probability of selecting two Phillips head screw.</em>
- <em>Probability of selecting three Phillips head screw.</em>
Now P(selecting 2 Phillips head screw with replacement) is given by :
Selecting 2 Phillip head screw =
*
=
P(selecting three Phillips head screw) =
*
*
=
Therefore, Probability that there will be more than one Phillips head screw
=
+
=
= 0.1803 .
