A fair coin is flipped 20 times. Your friend proposes a bet where if it lands on heads exactly 10 times, you win $4, but if it lands on heads 11 or more times or 9 or less times, you lose $1. Should you take the bet? In other words, find the expected value of the bet and if it is positive you should take it.

E[y]=∑yp(y)=4(0.176)+(−1)(0.824)  =−.12  dollar, so In one play the player is expected to lose 12% of a dollar.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
