Binomial Probability- I WILL GIVE BRAINLIEST ASAP PLS (1) The college health center did a survey and found that 14% of students smoke cigarettes.

A group of 9 students randomly sit at the same table. Find the probability that:

a) five students at the same table smoke

b) less than 3 students at the table smoke

(2) The probability of an adverse reaction to a pneumonia shot is 0.1

Pneumonia shot is given to a group of 12 people. What is the probability that:

a) none of them have an adverse reaction

b) exactly 5 of 12 people have an adverse reaction.

c) 2 or fewer of 12 people have an adverse reaction.

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
