Three equity analysts A, B and C are regularly asked about their
assessments with regard to the further development of a security
for the following day in the form of an “up” or “down”. It turns
out that analyst A is 80% likely to expect a rising price if the
other two analysts B and C agree in their assessment (ie both “up”
or both “down”). If, on the other hand, the two opinions diverge, A
expects a price increase of only 20%. It can also be seen that the
assessments of the three analysts are made independently in pairs,
with a 50% probability of a rising price and a 50% probability of a
falling price. The following applies under these circumstances:
1)the probability that all three analysts expect a falling price
is less than 5%, true or false
2)the probability that the three analysts agree in their assessment
is more than 50%,   true or false
3)the analysts B and C decide completely analogously to A, i. H. B
according to the congruence or discongruity of A and C and C
according to A and B (80% or 20%).   true or false
