Answer
$0.678$
This event is likely to occur.
Work Step by Step
First we find the probability that none of the flowers is a rose:
$p=\frac{26}{34}\times\frac{25}{33}\times\frac{24}{32}\times\frac{23}{31}=0.322$
The probability that at least 1 of the flowers is a rose would be the complement: $1-0.322=0.678$
This event is likely to occur because the probability is larger than 0.5.
