From sky divers having a terminal velocity of 200km/h, we should be able to determine their drag coefficient since we know their density to be roughly the same as water and the air density they are moving through. So, once we have the drag coefficient should we not be able to determine their terminal velocity through salt water? Can somebody calculate this for me or point me to a link that has the answer?

1) A bag contains 10 red,5 white and 4 blue balls. if 4 balls are drawn at random, determine the probabilty that (i) all 4 are blue balls and (ii) 1 red and 2 white.
2) In an experiment on pea breeding, Mendel obtained the following frequencies of seeds: 315 round and yellow; 101 wrinkled and green; 32 wrinkled and yellow ; total were 556 seeds.(we will get round and gree by subtracting from total, i think). Theory predicts that the frequencies would be in the proportion 9:3:3:1.Does the experimental results support the theory? please give all details needed. thank so much who solves.

I'm studying a MSc after a long time away from college (mature student) and I'm coming across Differential equations time-and time again - I vaguely remember doing these in my final year of college but that was over 10 years ago.
Has anyone got any tips on a 'BEGINNERS' guide on how to approach these equations?

It has been estimated that about 30% of frozen chicken contain enough salmonella bacteria to cause illness if improperly cooked. A consumer purchases 12 frozen chickens. What is the probability that the consumer will have more than 6 contaminated chickens? solve the question on basis of binomial probabilty distribution or probability.

Any sites that show statistics of the success rates of the use of both adult and embryonic stem cell for various diseases?

Like how many 'deaths' [failures or a disease caused by misuse of stem cell research, which resulted in death], per 'save'? [cure of original disease with no life -threatening side effects]...

My theory is that other intelligent life may already know about us and they just dont want to contact us. Why this could be the case I have no idea, but it was just a thought !
