The phrase "a weaker probability" is correct and usable in written English.
It can be used when discussing the likelihood of an event occurring, particularly in contexts such as statistics, risk assessment, or decision-making.
Example: "Given the current data, we can conclude that there is a weaker probability of success for this project compared to the previous one."
Alternatives: "a lower likelihood" or "a diminished chance".
It has been shown that a weak probability of making an error could improve the chance of discovery of better food sources even if it sometimes results in a sub-optimal response [69], [70].
For the two cytokeratin markers, the Markov model suggests the lack of a true reversible property of these variables as there was only a very weak probability of a patient returning to state 'low marker level' once having entered state 'high marker level'.
A relaxed cutoff of 2.24, corresponding to a weaker motif (0.1 probability of occurring by random chance) was also determined.
He says the principle is sometimes used in a weaker sense, requiring only that the probability of A and of B be raised by the occurrence of C, but he says, that the independence can usually be established "by the use of a more detailed description [of] the cause C" (p. 161, n.2).
However, because their monophyly is supported by very weak probabilities (BP<50%), we cannot rule out the possibility of their non-monophyly and the occurrence of multiple invasions into the freshwater habitats of Southeast Asia.
Such an approach was a key factor in deciding to use AIM-SNPs for the requested population comparison and in making the final ancestry assignments with confidence by not reporting three SNP profiles with the weakest probabilities (case samples 1, 4 and 6).
Lastly, the very low utilisation of bed net (e.g. 5.7% of children) is also a statement for a weak variability of the probability to be infected during the three years follow-up.
Secondary structure predictions for helix 1 show a weak "β sheet" (the probability is 0.4 sheet compared to 0.3 helix; 1 is high, 0 is low) for position 5 8 a.a. of Hsp40_Rat and 17 20 a.a. of CSPα_Rat, while predictions are stronger for helices 2, 3 and 4 (probability is 1, 1 and 0.7 respectively).
An allelic difference detected in GWAS might only have a weak effect on the probability of getting the disease.
