Answer:
Step-by-step explanation:
624 students
Since they’re only 3 parts more girls then boys and the number equals 144, you just have to divide 144 by 3. You’ll get 48

Answer: is it 0.258
Step-by-step explanation:
Answer:
Probability will be 0.5779
Step-by-step explanation:
Number of tablets n = 19
Probability of defect rems that is p = 0.03
Here number of trials is fixed and probability of success = 0.03
Here p = 0.03
So q = 1 - p = 1 -0.03 = 0.97
By using binomial distribution
Probability is given by ![^nC_rp^rq^{n-r}](https://tex.z-dn.net/?f=%5EnC_rp%5Erq%5E%7Bn-r%7D)
So P(0 or 1) = ![^{19}C_0{0.03}^0{0.97}^{19-0}+^{19}C_1{0.03}^1{0.97}^{19-1}=0.5606+0.0173=0.5779](https://tex.z-dn.net/?f=%5E%7B19%7DC_0%7B0.03%7D%5E0%7B0.97%7D%5E%7B19-0%7D%2B%5E%7B19%7DC_1%7B0.03%7D%5E1%7B0.97%7D%5E%7B19-1%7D%3D0.5606%2B0.0173%3D0.5779)
Complement angles, sum is equal 90
Give one angle = 70 to find other: 90 - 70 = 20
Answer
