From the table given
17 people have managed care plan
9 have Traditional insurance
6 have no insurance
The probability of an event happening is given as the ratio of the number of the possible outcome divided by the total outcome.
If two balls are taken, the probability that at least one has traditional insurance
TN or TM or TT or NT or MT
where T is for traditional insurance
N is for no insurance
M is for managed insurance
the probability that at least one of two people picked without replacement has traditional insurance
= 9/32 * 6/31 + 9/32 * 17/31 + 9/32 * 8/31 + 6/32 * 9/31 + 17/32 * 9/31
= (54 + 153 + 72 + 54 + 153)/992
= 486/992
= 243/496
Answer:
E. 0.759
Step-by-step explanation:
You can take this right triangle to have a base length side LM , height of LN and a hypotenuse of MN
The sine of angle ∠LMN is 0.759, find the value of ∠LMN
∠LMN=49.38°
Find angle ∠LNM
You know sum of angles in a triangle add up to 180°, given that this is a right-triangle, the base angle is 90° hence
∠LNM=180°-(90°+49.38°)
∠LNM= 180°-139.38°=40.62°
Find cos 40.62°
Cos 40.62°=0.7590
56 is you answer you need.
